Several thoughts here. 1. You can use globbing functions to remove selected parts of the cache using wildcards - see clearGlob() method in sfToolkit. 2. You could also skip action caching and cache selected parts of the page instead (i.e. parts not dependant on session data and partials not dependant on session data). 3. Setup (2) and build a module that has actions to clear portions of the cache depending on changes in the model data - you need to create unique keys for the page portions you wish to clear. I did all of the above on a large site Im working on, i.e. no action caching; break down and analyse portions of each template then code your templates / actions / partials to use caching when necessary; and set cache keys for each fragment. In our case, the main site only has a few templates so its not as hard as you might think. Whenever a user changes data that is normally cached, the action calls another action in a "cache clearing" module that removes the cache entry (I pass cache key or an id used in the cache key to the clearing action). The next time someone hits that content, the cache is regenerated automatically. So far this scheme has worked very well (number of queries on some pages become 0). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "symfony users" group.
