This bundle makes two changes to Symfony2's default HTTP cache (currently supporting Symfony versions 2.1 and 2.2):
- Allows parts of a view to be cached through ESI, even if the master response
has a "private" Cache-Control header (Symfony2 will be default force the
entire response to be public). This replicates the
sf_cache_keybehaviour of Symfony of 1.4 which allowed for easy partial caching. (Important: Use release 0.1.1 if you want this feature. It has been removed from later versions, as Symfony now supports it out of the box). - Makes it possible to use ESI within JSON responses
Disclaimer: Please only use this bundle if you have a solid understanding of ESI caching, as it removes some of the safeguards put in place by default with Symfony2. If you were to, for example, include a user's private content via ESI without a cache key that's unique to them, that content is likely to leak through to other users.
