* Update documentation to ActionController::ConditionalGetAnatoly Mikhaylov2018-09-031-0/+6
| | | | Two implemented but undocumented features are to help indicate that cache is fresh for 3 hours, and it may continue to be served stale for up to an additional 60 seconds to parallel requests for the same resource or up to 5 minutes while errors are being returned back while the initial synchronous revalidation is attempted.
* Add support for more HTTP cache controlsDaniel Schierbeck2018-06-131-1/+3
| | | | | | | | | | | | | | | | | | From <https://tools.ietf.org/html/rfc5861>: > The stale-if-error HTTP Cache-Control extension allows a cache to > return a stale response when an error -- e.g., a 500 Internal Server > Error, a network segment, or DNS failure -- is encountered, rather > than returning a "hard" error. This improves availability. > > The stale-while-revalidate HTTP Cache-Control extension allows a > cache to immediately return a stale response while it revalidates it > in the background, thereby hiding latency (both in the network and on > the server) from clients. These are useful, fully standardized parts of the HTTP protocol with widespread support among CDN vendors. Supporting them will make it easier to utilize reverse proxies and CDNs from Rails.

* Strong ETag validatorsJeremy Daer2016-03-311-13/+46
| | | | | | | | | | | | | | | | | | * Introduce `Response#strong_etag=` and `#weak_etag=` and analogous options for `fresh_when` and `stale?`. `Response#etag=` sets a weak ETag. Strong ETags are desirable when you're serving byte-for-byte identical responses that support Range requests, like PDFs or videos (typically done by reproxying the response from a backend storage service). Also desirable when fronted by some CDNs that support strong ETags only, like Akamai. * No longer strips quotes (`"`) from ETag values before comparing them. Quotes are significant, part of the ETag. A quoted ETag and an unquoted one are not the same entity. * Support `If-None-Match: *`. Rarely useful for GET requests; meant to provide some optimistic concurrency control for PUT requests.

* Implement http_cache_forever to ActionControllerArthur Neves2015-02-151-0/+18
| | | | | | | | | Add http_cache_forever to ActionController, so we can cache results forever. Things like static pages are a good candidate for this type of caching. This cache only controls caching headers, so it is up to the browser to cache those requests.
* Accept a collection in fresh_when and stale?claudiob2015-02-101-10/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The methods `fresh_when` and `stale?` from ActionController::ConditionalGet accept a single record as a short form for a hash. For instance ```ruby def show @article = Article.find(params[:id]) fresh_when(@article) end ``` is just a short form for: ```ruby def show @article = Article.find(params[:id]) fresh_when(etag: @article, last_modified: @article.created_at) end ``` This commit extends `fresh_when` and `stale?` to also accept a collection of records, so that a short form similar to the one above can be used in an `index` action. After this commit, the following code: ```ruby def index @article = Article.all fresh_when(etag: @articles, last_modified: @articles.maximum(:created_at)) end ``` can be simply written as: ```ruby def index @article = Article.all fresh_when(@articles) end ```
* Fix wrong kwarg "record" from #18872claudiob2015-02-101-1/+1
| | | | | | | | | | | | PR #18772 changed the parameters of `stale?` to use `kwargs`. [As for this comment](https://github.com/rails/rails/pull/18872/files#r24456288) the default value for the `etag` parameter should be `record`, not `nil`. This commit fixes the code and introduces a test that: - passed before #18872 - fails on the current master (after #18772) - passes again after setting the default value of `etag` to `record`.

|
* Better examples for fresh_when and stale?claudiob2015-01-061-2/+2
| | | | | | | | | | It is clearer and closer to reality to use `@article.updated_at` as the `:last_modified` parameter of `fresh_when` and `stale?`. Using `@article.created_at` would result in the cache never expiring, since the creation timestamp never changes. [ci skip]

* Consistently capitalize ETag.Steven Harman2014-09-161-3/+3

* When your templates change, browser caches bust automatically.Jeremy Kemper2014-08-171-6/+31
| | | | | | | | | | | | | | | | New default: the template digest is automatically included in your ETags. When you call `fresh_when @post`, the digest for `posts/show.html.erb` is mixed in so future changes to the HTML will blow HTTP caches for you. This makes it easy to HTTP-cache many more of your actions. If you render a different template, you can now pass the `:template` option to include its digest instead: fresh_when @post, template: 'widgets/show' Pass `template: false` to skip the lookup. To turn this off entirely, set: config.action_controller.etag_with_template_digest = false

* Replace comments' non-breaking spaces with spacesclaudiob2012-12-041-1/+1
| | | | | | | | | | Sometimes, on Mac OS X, programmers accidentally press Option+Space rather than just Space and don’t see the difference. The problem is that Option+Space writes a non-breaking space (0XA0) rather than a normal space (0x20). This commit removes all the non-breaking spaces inadvertently introduced in the comments of the code.
