* Allow using combine the Cache-Control `public` and `no-cache` headersyuuji.yaginuma2019-01-071-4/+6
| | | | | | | | | | | | | | | | | Since #30367, if `no-cache` includes Cache-Control headers, special keys like `public`, `must-revalidate` are ignored. But in my understanding, `public` still need in case of want to cache authenticated pages. The authenticated pages to be cacheable, but still authenticated for every user, need to specify the `Cache-Control: public, no-cache`. For keys other than `public`, I did not know the case where it was necessary to use it in combination with `no-cache`, so I fixed that can be used only for `public`. Ref: https://www.mnot.net/cache_docs/#CACHE-CONTROL Fixes #34780.
* Add `Style/RedundantFreeze` to remove redudant `.freeze`Yasuo Honda2018-09-291-9/+9
| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen. This magic comment is enabled by `Style/FrozenStringLiteralComment` cop. * Exclude these files not to auto correct false positive `Regexp#freeze` - 'actionpack/lib/action_dispatch/journey/router/utils.rb' - 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb' It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333 Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed. * Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required - 'actionpack/test/controller/test_case_test.rb' - 'activemodel/test/cases/type/string_test.rb' - 'activesupport/lib/active_support/core_ext/string/strip.rb' - 'activesupport/test/core_ext/string_ext_test.rb' - 'railties/test/generators/actions_test.rb'
* Add support for more HTTP cache controlsDaniel Schierbeck2018-06-131-1/+5
| | | | | | | | | | | | | | | | | | 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.

|\ | | | | Normalize/process Cache-Control headers consistently
| * Don't touch an unused headerPatrick Toomey2017-08-231-1/+0
| | | | | | | | | | | | The prior logic explictly set `Cache-Control` to `nil`. But, we would only reach that logic if the header was not set to begin with. So, rather than give it any value at all, just leave it alone.
| * Decouple the merge/normalization and conditional cache control logicPatrick Toomey2017-08-231-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The prior logic was trying to do too many things at once. For all responses, we want to perform two distinct steps: * Merge/normalize the `Cache-Control` values found in HTTP headers and those found in the `@cache_control` hash. * Conditionally set a default `Cache-Control` header value when we have an ETag This change separates these concerns since the merge/normalize step should occur for all responses, but the second should only occur when we have already set an ETag/last modified value. Normally ETag middleware will set a default `Cache-Control`, but only if an existing ETag is not already set. So, in the cases where an ETag is set, we need to set the default `Cache-Control` value ourselves.

| * Normalize/process Cach-Control headers consistentlyPatrick Toomey2017-08-221-3/+1
| | | | | | | | | | | | | | | | | | | | In the existing logic, the `Cache-Control` header may or may not get normalized by additional logic depending on whether `response.cache_conrol` has been modified. This leads to inconsistent behavior, since sometimes `Cache-Control` can contain whatever a user sets and sometimes it gets normalized, based on the logic inside of `set_conditional_cache_control!`. It seems like this normalization process should happen regardless to ensure consistent behavior.

* Strong ETag validatorsJeremy Daer2016-03-311-15/+49
| | | | | | | | | | | | | | | | | | * 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.

* Ensure that cache-control headers are mergedJames Tucker2012-06-181-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are several aspects to this commit, that don't well fit into broken down commits, so they are detailed here: * When a user uses response.headers['Cache-Control'] = some_value, then the documented convention in ConditionalGet is not adhered to, in this case, response.cache_control is ignored due to `return if self[CACHE_CONTROL].present?` * When a middleware sets cache-control headers that would clobber, they're converted to symbols directly, without underscores. This would lead to bugs. * Items that would live in :extras if set through expires_in, are placed directly in the @cache_control hash, and not respected in many cases (somewhat adhering to the aforementioned documentation). * Although quite useless, any directive named 'extras' would be ignored. The general convention applied is that expires_* take precedence, but no longer overwrite everything and expires_* are ALWAYS applied, even if the header is set. I am still unhappy about the contents of this commit, and the code in general. Ideally it should be refactored to no longer use :extras. I'd likely recommend expanding @cache_control into a class, and giving it the power to handle the merge in a more efficient fashion. Such a commit would be a larger change that could have additional semantic changes for other libraries unless they utilize expires_in in very standard ways.
