There are other ways to clear cache... What we did was to write a 'clear cache' module, so updating a single item will automatically clear all associated pages by calling a specific URL in our 'cc' module with parameters specifying the object in question (since we know what cache keys we have used this is easy to do). Typically, thanks to globbing, the actual call to clear a cached object is just one or two method calls. Since partials are used across the site, clearing it once, clears it for all pages that use it, and the next request for it generates cache once for all pages that use it. The actions in the cc module are built from primitives that clear a specific object (like a template fragment or a partial), so a page clearing action might call a few primitives to update the whole page. In our case, our site is heavy wth content, so we have actions in the cc module to clear pages, category pages, specific partials on the home page, the whole homepage, etc etc. We used a filter to secure the module, so only HTTP GET requests from our backend app (on a separate secure server) is allowed to access those URLs. -- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "symfony users" group.
