Provides HTTP cache handling for eZ Platform, by default since version 1.12. It adds support for multi-tagging for Symfony Proxy, Varnish (using xkey). Support for Fastly is part of the eZ Platform Cloud Enterprise offer as of 1.13 LTS.
For usage with Varnish see the dedicated document in docs/varnish
Responses from /content/view will be tagged based on their contents:
curl -i -X HEAD 'http://localhost:8000/'
HTTP/1.1 200 OK
Host: localhost:8000
Connection: close
Cache-Control: public, s-maxage=60
Content-Type: text/html; charset=UTF-8
Vary: X-User-Context-Hash
xkey: ez-all c1 ct1 l2 pl1 p1 p2
If you have several repositories configured, the tags will be prefixed by repository "index" on non default repository. E.g. "1p1", where repository is the second repository in the system (default repository has index 0 but does not have prefix).
For further reading on tags see docs/using_tags.md.
Responses from /content/view will be made cachable, and the shared max age will be set if it is enabled.
A set of Slots will send HTTP PURGE requests for each cache tag affected by write operations.
This bundle lets you configure drivers for handling HTTP cache. The following exists from eZ:
local: extended Symfony Proxy to support tagging and varying by user rights (available in this bundle)varnish: Varnish proxy using and customizing FosHttpCache for purging (available in this bundle)fastly: Fastly CDN proxy (available with eZ Platform Enterprise and documented separately)
Configuring these is done using global ezpublish.http_cache.purge_type config. By default it is set to use
%purge_type% parameter, and can be set in app/config/parameters.yml like so:
parameters:
purge_type: varnish
