From 2a272b238c017ecee310775acf8a0d4631bb27b4 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Aug 2026 23:23:00 +0000 Subject: [PATCH 1/6] docs: RFC spec for HTTP caching primitives (ETag, Last-Modified, Cache-Control) Drafts event.etag()/lastModified()/cacheControl() on RequestContext and Response, plus an automatic layer built on the existing Event Caching annotation surface (cache="true", cacheTimeout, ...). Automatic caching splits into two honestly-different tiers: Tier 1 piggybacks on Bootstrap's existing pre-execution cache lookup to skip both handler execution and body replay on a conditional-GET hit, for free; Tier 2 (no Event Caching) computes an ETag per-request and only saves the client a body download, not server compute - documented explicitly so "automatic" doesn't overpromise. Spec only. No framework code changes.

Motivation + +A case-insensitive grep across `system/` for `etag`, `last-modified`, `cache-control`, +`if-none-match`, `if-modified-since`, and `304` returns **zero hits** (the lone `"304"` string +anywhere in the codebase is a status-text lookup entry, unrelated to caching). ColdBox has no +concept of HTTP-level conditional requests or cache negotiation. Every response — cached +server-side or not — always sends a full `200` with a full body. + +That is a real gap for anything that talks to a browser, CDN, or reverse proxy: API resources +that rarely change, static-ish content endpoints, polling clients, HTMX partials. All of them +would benefit from being able to say "you already have this" (`Cache-Control`) or "ask me, and +I'll say 304 if nothing changed" (`ETag` / `Last-Modified`). + +### This is not Event Caching, and must not be confused with it + +ColdBox already ships a caching system that looks adjacent but solves a different problem, and +this spec's central design move is to sit *on top of* it rather than duplicate it. + +**Event Caching** (`cache="true"` on a handler action, `system/Bootstrap.cfc:243-403`) caches the +**server's own rendered output** in CacheBox so ColdBox can skip re-running the handler and +re-rendering the view on a hit. It is a *server compute* optimization. It has nothing to say to +the client — a cache hit still ships a full `200` response with the full body over the wire, +every time, forever, to every client, even one that already has last minute's identical bytes. + +**HTTP Caching** (this spec) is the *client-facing* layer: it lets the browser, a CDN, or a +reverse proxy skip the round trip entirely, or lets the server skip sending the body when the +client can prove it already has the current representation. It is orthogonal to whether the +server itself re-computed that representation. + +They compose. §4 is built entirely around the observation that Event Caching's existing +machinery — a pre-execution cache lookup, sitting in memory with the full rendered body, before +ColdBox has committed to sending it — is exactly the leverage point HTTP caching needs, and that +combining the two is nearly free. + +### Non-goals + +- **Not** a route-level cache-rules system (`cache`/`cacheTimeout`/`cacheKey` as route-struct + keys, à la Nitro's `routeRules`). That is a separate, later recommendation that would *consume* + the primitives this spec defines — it is not designed here. +- **Not** replacing or deprecating Event Caching. Every existing `cache="true"` handler keeps + working exactly as it does today if it never opts into anything this spec adds. +- **Not** CDN/reverse-proxy configuration, surrogate keys, or cache purging APIs. +- **Not** content negotiation via `Vary` on representation (gzip/br, `Accept`-based format + switching). `Vary` is mentioned only as a correctness caveat in §4.5. + +--- + +## 2.

The automatic layer + +This is the part worth building carefully, because there are two genuinely different cost +profiles hiding under one word ("automatic"), and conflating them would make a false promise +about what the framework is actually saving. + +### 4.1 Annotations extend the existing cache metadata block + +Event Caching's annotation defaults live in `getNewMDEntry()` (`HandlerService.cfc:764-776`) and +are read in `getEventCachingMetadata()` (`:801-811`): + +```java +// Existing, unchanged +cache : false, +cacheTimeout : "", +cacheLastAccessTimeout : "", +cacheProvider : "template", +cacheInclude : "*", +cacheExclude : "", +cacheFilter : "", +``` + +New siblings, added to the same struct and read the same way (as function-level annotations): + +```java +// New +etag : false, // boolean, or "auto" — see tiers below +etagWeak : false, // boolean +lastModified : "", // "" (off), "true" (tier-1 only), or a private-method name (tier-2, mirrors cacheFilter's closure-by-name pattern) +cacheControl : "", // raw Cache-Control value, e.g. "public, max-age=60" +``` + +Declaration is unchanged CFML annotation-on-function syntax, identical in spirit to how +`cache`/`cacheTimeout` already read today: + +```java +function index( event, rc, prc ) + cache="true" + cacheTimeout="30" + etag="true" +{ + ... +} +``` + +### 4.2 Tier 1 — cache-integrated automatic ETag (the free win) + +This is the deep insight the rest of the section builds on: `Bootstrap.cfc:245-289` **already** +performs a pre-execution CacheBox lookup, keyed by `EventURLFacade.buildEventKey()` + +`getUniqueHash()` (`EventURLFacade.cfc:136-145`, `:44-96` — event name + module + a filtered hash +of RC params + host), *before* `runEvent()` is ever called. On a hit, the full `renderedContent`, +`statusCode`, `contentType`, and `responseHeaders` are already sitting in memory, about to be +replayed verbatim (`Bootstrap.cfc:361`). + +Piggy-backing an ETag onto that entry costs almost nothing, because the hash is computed **once, +at write time**, not on every subsequent request: + +**On cache write** (`Bootstrap.cfc:340-378`, alongside the existing `cacheBox...set(...)` call at +`:370-377`): if `etag="true"` is set on the action, compute `hash( renderedContent, "MD5" )` once +and store it as an `etag` field on the same cache entry struct that already holds +`renderedContent`/`contentType`/`statusCode`. + +**On cache hit** (`Bootstrap.cfc:245-289`, before the existing replay at `:290+`): if the stored +entry carries an `etag`, compare it against `getHTTPHeader( "If-None-Match", "" )` *before* +writing the body. + +- **Match** → skip the replay entirely. Send a bare `304` with just `ETag` (and `Cache-Control`, + if set) — no body write at all. This is strictly *cheaper* than what happens today on every + cache hit, for zero extra request-time cost, because the hash already existed. +- **No match / absent `If-None-Match`** → replay the full body exactly as today, but now also + emit the stored `ETag` header, so the *client's next* request can 304. + +``` +Request arrives + │ + ├─ eventCachingTest() (RequestService.cfc:145) says cacheable? + │ │ + │ ├─ NO → run handler + render normally (untouched by this spec) + │ │ + │ └─ YES → look up cache entry + │ │ + │ ├─ MISS → run handler + render + │ │ → on write: if etag="true", hash body once, store on entry + │ │ → send 200 + body (+ ETag header if etag="true") + │ │ + │ └─ HIT + │ ├─ etag NOT set on entry → replay body exactly as today (unchanged) + │ │ + │ └─ etag set on entry → compare If-None-Match + │ ├─ match → 304, no body (NEW — cheaper than today's replay) + │ └─ no match → replay body + ETag header (as before, now with ETag) +``` + +This only activates when `etag="true"` is *explicitly* opted into alongside `cache="true"` — +existing `cache="true"` handlers that never touch this new annotation see no behavior change at +all, on either the write or read path. + +### 4.3 Tier 2 — standalone automatic ETag (no Event Caching involved) + +Some handlers can't or shouldn't use Event Caching — output that's too per-user-specific for the +RC-hash cache key to be meaningful, or content that must always be freshly computed server-side +but still benefits from *client-side* conditional-GET. For these, `etag="true"` without +`cache="true"` computes the hash **after** rendering, on every request, and checks it against +`If-None-Match` before the body is written to the client. + +This needs a hook *after* the rendered body exists but *before* it's written to the wire. +Event Caching itself is not wired through an announced interception point — it's inline in +`Bootstrap.cfc` — so Tier 2 has the same structural choice Event Caching already made: either add +a small, explicit check inline in `Bootstrap.cfc`'s render path (mirroring how the cache-write +branch works, just without CacheBox), or introduce a new interception point +(`preResponseWrite`, firing after `renderedContent` is final and before `writeOutput()`) that a +core, conditionally-registered interceptor listens on. The latter is more consistent with how the +SSE work extended the interception-point ENUM (`InterceptorService.cfc:44-92`) rather than adding +inline branches, and is the recommended approach — left as an implementation decision, not a +design gap, since either is mechanically straightforward. + +**This tier's cost model is genuinely different, and must be documented as such**: the handler +and the full render *still run on every request* — Tier 2 saves the client a body download, but +saves the server nothing. Framework documentation and the annotation's own doc comment should say +this explicitly, so nobody enables `etag="true"` on a hot, expensive, uncached endpoint expecting +Event-Caching-level savings and is disappointed. + +### 4.4 Automatic Last-Modified + +Two sources, matching the two tiers: + +- **Tier 1 (free):** when `cache="true"` and `lastModified="true"` (boolean form) are both set, + the cache entry's write timestamp is exposed as `Last-Modified` for free. CacheBox object stores + already record a `created` timestamp on every entry as standard metadata (used for eviction + policies like `FIFO.cfc`, and retrievable via `getObjectMetadata()`) — this reuses that existing + value rather than tracking a new one, the same way §4.2 reuses a hash computed once at write + time rather than per-request. +- **Tier 2 (developer-supplied):** `lastModified="getProductModifiedDate"` names a private handler + method, mirroring the existing `cacheFilter` closure-by-name convention + (`HandlerService.cfc:824-851`), returning a `date`. Useful when the true "last changed" moment + is a database column, not "whenever this happened to render": + + ```java + function show( event, rc, prc ) + lastModified="getProductModifiedDate" + { + prc.product = productService.get( rc.id ) + event.setView( "products/show" ) + } + + private date function getProductModifiedDate( event, rc ){ + return productService.get( rc.id ).getModifiedDate() + } + ``` + + This form necessarily runs before the main action body (it needs `rc.id` to know *which* + product), so it participates in Tier 2's cost model even when combined with `cache="true"` — + unlike the boolean form, a closure-supplied `Last-Modified` cannot be deferred to cache-write + time because it depends on data the framework doesn't otherwise fetch. + +### 4.5 Automatic Cache-Control + +The simplest of the three — pure header assembly, no negotiation logic, no client round-trip +involved. If `cacheControl` is set, the framework attaches it verbatim. As a convenience default: +when `cache="true"` and `cacheTimeout` are set with no explicit `cacheControl`, default +`Cache-Control: private, max-age={cacheTimeout in seconds}` — "you already told me how long to +keep this server-side; telling the client the same number by default is a reasonable inference, +always overridable by setting `cacheControl` explicitly." + +**Correctness caveat, not optional:** any response whose `Cache-Control`/`ETag` genuinely differs +per requester (auth state, locale, `Accept`-negotiated format) must either use `private` rather +than `public`, or set `Vary` accordingly. This spec does not attempt to infer that automatically — +`private` is the conservative default in the auto-derivation above precisely to avoid a framework +default ever causing a cross-user cache leak. `public` is opt-in only. + +### 4.6 Annotation reference + +| Annotation | Type | Default | Tier | Requires | +|---|---|---|---|---| +| `etag` | `boolean` | `false` | 1 if paired with `cache="true"`, else 2 | — | +| `etagWeak` | `boolean` | `false` | — | `etag="true"` | +| `lastModified` | `boolean` \| method name | `""` | 1 (boolean form + `cache`) or 2 (method-name form) | — | +| `cacheControl` | `string` | `""` (falls back to the §4.5 default when `cache`+`cacheTimeout` set) | — | — | + +### 4.7 Settings block + +Sibling to the existing `this.eventCaching` (`Settings.cfc:35`) and the SSE feature's +`this.sse` block: + +```java +this.httpCaching = { + "enabled" : true, + // Global opt-in: enable Tier 2 automatically for every rendered GET/HEAD + // response that doesn't otherwise set an etag annotation. Off by default - + // this changes response bytes for every endpoint in the app. + "autoETag" : false, + "defaultCacheControl" : "private, no-cache", + "weakETagsByDefault" : false +}; +``` + +--- + +## 5. Route-level equivalent + +Out of scope for this spec's implementation, but the seam is worth naming: a future route-level +cache-rules feature (route-struct `cache`/`cacheTimeout`/`cacheKey`, à la Nitro's `routeRules`) +would declare `etag`/`lastModified`/`cacheControl` as route-struct keys the same way `sse` and +`sseCallback` were added to `initRouteDefinition()` — and would need those keys declared as +`addRoute()` parameters too, per the drift class fixed in `Router.cfc` (`ai`/`mcp`/`sse` all hit +this same footgun; see the `getRouteDefinitionKeys()` guard test added specifically to catch it +happening again). + +--- + +## 6. Interaction with `RestHandler` + +The same integration hazard class the SSE spec found (`docs/specs/sse-streaming.md §6`) applies +here, for the same underlying reason: `RestHandler.aroundHandler` (`RestHandler.cfc:40`) +unconditionally calls `event.renderData(...)` at `:142-150` whenever the action set no view, no +render data, and returned nothing — which describes a 304 short-circuit just as well as it +describes a stream. + +A `304` must happen **before** `aroundHandler` reaches that render step, not through the +`Response` object's buffered headers (§3.2), since those are only flushed *after* the render call. +The pattern: + +```java +function show( event, rc, prc ){ + prc.product = productService.get( rc.id ) + if ( event.etag( prc.product.getHash() ) ) { + return // noExecution() + 304 already set — aroundHandler must not marshal a body + } + prc.response.setData( prc.product ) +} +``` + +`event.etag()`/`event.lastModified()` already call `noExecution()` (§3.1), and +`RestHandler.aroundHandler` already has an `isSSE()`-style guard point (added by the SSE work, +`RestHandler.cfc` immediately after the response timer) that is the natural place to add a +parallel check. `isNoExecution` today is only a `property` (`RequestContext.cfc:38`) — the +accessor-generated getter is `getIsNoExecution()`, not a bare boolean predicate — so this spec +needs to **add** a small `isNoExecution()` method (mirroring `isSSE()`'s own existing shape) +rather than reuse something that already exists in that form: + +```java +// RequestContext.cfc — new +boolean function isNoExecution(){ + return variables.isNoExecution; +} +``` + +```java +// RestHandler.cfc — end timer +arguments.prc.response.setResponseTime( getTickCount() - stime ) + +// A 304 (or an SSE stream) has already committed the response - no marshalling. +if ( arguments.event.isSSE() || arguments.event.isNoExecution() ) { + return +} +``` + +--- + +## 7. Examples + +### 7.1 Manual ETag, plain handler + +```java +function show( event, rc, prc ){ + prc.product = productService.get( rc.id ) + if ( event.etag( prc.product.getHash() ) ) { + return + } + event.setView( "products/show" ) +} +``` + +### 7.2 Tier 1 — Event Caching + automatic ETag, for free + +```java +function index( event, rc, prc ) + cache="true" + cacheTimeout="300" + etag="true" +{ + prc.products = productService.list() + event.setView( "products/index" ) +} +``` + +First request: cache miss, handler runs, body hashed once at write time, `ETag` sent. +Every subsequent request within the 300s window: cache hit, hash comparison only — no handler +execution, no render, and (on a match) no body write either. + +### 7.3 Tier 2 — automatic Last-Modified via closure, no Event Caching + +```java +function show( event, rc, prc ) + lastModified="getArticleModifiedDate" +{ + prc.article = articleService.get( rc.id ) + event.setView( "articles/show" ) +} + +private date function getArticleModifiedDate( event, rc ){ + return articleService.get( rc.id ).getModifiedDate() +} +``` + +### 7.4 REST resource with conditional GET + +```java +component extends="coldbox.system.RestHandler" { + + function show( event, rc, prc ){ + prc.order = orderService.get( rc.id ) + if ( event.etag( prc.order.getVersion() ) ) { + return + } + prc.response.setData( prc.order ) + } + +} +``` + +### 7.5 App-wide Tier 2 opt-in + +```java +// config/Coldbox.cfc +this.httpCaching = { + "enabled" : true, + "autoETag" : true // every rendered GET/HEAD response gets a computed ETag, + // no per-handler annotation required +}; +``` + +--- + +## 8.

Testing strategy + +Following the pattern established for SSE (`tests/specs/web/context/RequestContextSSETest.cfc` +et al.), but with **no BoxLang gate** — this feature is pure HTTP header logic with no runtime +dependency, so specs run on every engine in the matrix. + +- **`RequestContextHTTPCachingTest.cfc`** — `etag()`/`lastModified()`/`cacheControl()` against a + mocked request context, covering: match → 304 + `noExecution()`; no-match → header set, request + proceeds; weak vs strong tag formatting; absent conditional header behaves as no-match; unsafe + HTTP methods never short-circuit. +- **Bootstrap-level integration test** — a `cache="true" etag="true"` handler, asserting: first + request executes and stores a hash; second identical request (no `If-None-Match`) still replays + the body but now carries `ETag`; third request with a matching `If-None-Match` gets a `304` with + an empty body and the handler does not re-execute (assert via a call-count spy on the handler, + matching the existing Event Caching test suite's approach). +- **`RestHandlerTest.cfc`** — extend to cover the `isNoExecution()` guard in `aroundHandler`, + mirroring the existing `isSSE()` coverage. + +--- + +## 10. Open questions + +- **Interception point vs. inline `Bootstrap.cfc` check for Tier 2** (§4.3) — leaning inline, for + consistency with how Event Caching itself is implemented, but a new `preResponseWrite` point + would be more consistent with how *this session's* SSE work extended the ENUM. Worth deciding + before implementation, not during it. +- **Hash algorithm for auto-ETag** — `MD5` is fast and collision-irrelevant for cache validation + (not a security context), but should this be configurable (`this.httpCaching.hashAlgorithm`) for + shops with a compliance policy against MD5 anywhere in the codebase, even non-cryptographic + uses? +- **`cacheControl` as a struct vs. raw string annotation** — §4.1's table declares it as a raw + string for simplicity of annotation syntax (CFML function annotations are string-valued).

From 5e3fcb73676c87384c3f8590b968596c87532311 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 16 Aug 2026 00:40:45 +0000 Subject: [PATCH 2/6] feat: HTTP caching primitives - ETag, Last-Modified, Cache-Control (Tier 1) Implements the Tier 1 (Event Caching-integrated) automatic ETag/Last-Modified support from docs/specs/http-caching.md, plus the manual primitives: - RequestContext: event.etag()/lastModified()/cacheControl(), a new isNoExecution() predicate, and a portable toHTTPDate() formatter (built from individual date parts rather than a dateTimeFormat() mask - CFML's classic mask letters and Java's DateTimeFormatter pattern letters are different dialects, and which one a given engine's dateTimeFormat() implements isn't safe to assume across BoxLang/Lucee/Adobe). - Response: matching withETag()/withCacheControl() fluent helpers. - HandlerService: new etag/etagWeak/lastModified/cacheControl annotations alongside the existing cache/cacheTimeout event-caching annotations, gated by a new this.httpCaching.enabled global switch. - Bootstrap: on a cache write, computes an ETag hash and/or Last-Modified timestamp once and stores it on the cache entry; on a cache hit, compares the stored ETag against the incoming If-None-Match before touching the body at all - a match skips the replay entirely and sends a bare 304, which is cheaper than today's always-replay behavior. A handler that never sets these new annotations sees no behavior change. - RestHandler: aroundHandler now also guards on isNoExecution(), so a conditional-GET resolved inside an action doesn't hit the same write-after-commit hazard the SSE isSSE() guard already covers. - Settings/ApplicationLoader: this.httpCaching defaults block, parsed the same way as the existing this.sse block. Found and fixed two bugs while writing tests against real execution rather than assuming the code was correct: cacheControl()'s isBoolean(val) check is loosely true for any castable value (isBoolean(60) is true in CFML/BoxLang), which silently dropped numeric directive values like max-age=60 down to a bare "max-age" token; and the original dateTimeFormat() mask ("ddd, dd mmm yyyy...") threw "Too many pattern letters: d" on BoxLang, which is what led to the portable toHTTPDate() implementation instead. Tests: unit coverage for etag()/lastModified()/cacheControl()/isNoExecution()/ toHTTPDate() (engine-agnostic, no BoxLang gate - pure header logic), Response fluent header tests, RestHandler aroundHandler guard tests, and integration tests extending the existing EventCachingSpec with two new test-harness handler actions. The integration suite could not be executed in this sandbox (BaseIntegrationTest needs a real servlet CGI scope this CLI environment doesn't have - confirmed this is a pre-existing limitation by running the unmodified spec, which fails identically) but the new handler actions and helper methods were verified directly via bare instantiation. Full local regression suite: 195 passed, 4 failed/23 errors - unchanged against the established pre-existing baseline (21 errors) plus 2 newly bundled, unrelated, pre-existing RestHandlerTest sandbox-limitation errors.

This is true for every existing test in this file too: none of them read the cache store back, they all assert only against cbox_eventCacheableEntry, the pre-execution metadata flag. My three new tests assumed execute() would let them read back an actual stored ETag hash, which the harness structurally cannot provide - confirmed by getCache(...).get(cacheKey) returning nothing after execute(), on every engine identically. Rescoped to what's actually observable: the etag/etagWeak/lastModified/ cacheControl annotations correctly flow into the cacheable entry metadata, for both a handler that sets them and one that never does (verifying the defaults). The write-time hash computation and the conditional-GET short-circuit decision itself are still covered directly against RequestContext in RequestContextHTTPCachingTest.cfc, which does not have this limitation.

The two affected assertions hardcoded one specific order ("public, max-age=60"). Per RFC 9111, Cache-Control directive order carries no semantic meaning, so the fix is to assert both directives are present via toInclude() rather than an exact ordered string match, not to force a specific struct iteration order in the implementation.

The separate this.httpCaching.enabled toggle could never independently disable anything eventCaching didn't already disable, so it added a settings block, a config parser, and a docblock explaining a distinction that didn't exist. Removed all three; the annotations now read unconditionally, matching the existing cacheInclude/cacheExclude/cacheFilter convention exactly. Updated docs/specs/http-caching.md §4.7 to explain why Tier 1 needs no settings block, and moved the settings-block sketch to where it actually belongs: Tier 2, which - unlike Tier 1 - runs independently of cache="true" and eventCaching entirely, so it would genuinely need its own opt-in if built.

Bootstrap's cache-write path was passing now() (local time) straight through, and every call site benefits from the fix without changing its own code. - Bootstrap.cfc's cache-hit conditional-GET replay now calls event.etag()/event.lastModified() directly instead of re-implementing a narrower version of the same matching logic, so the automatic (event-cache-integrated) path and the manual API path can't drift apart again. This also fixes a real gap Copilot found: the cached entry's etagWeak flag was computed at write time but never persisted onto the cache entry, so a weak ETag was always replayed as strong on every subsequent hit; and Last-Modified was replayed as a header on a cache hit but never actually checked against If-Modified-Since, so an action using lastModified() without etag() never got a 304 from the cache-hit path at all. - docs/specs/http-caching.md: the spec's Status line and motivation section still said "no implementation yet" despite this PR shipping Tier 1; corrected to reflect Tier 1 as implemented and Tier 2 as the remaining unimplemented tier.
