After using EE 1.12 for a while I migrate to EE 1.13.1, using the default new backend Mage_Cache_Backend_File.
After a new order or a catalog modification, the whole FPC expire completely (all categories and products).
I understand that after an order or catalog modification the related product and categories's cache should be refresh or invalidated, but not the entire FPC.
Any idea what i'm doing wrong?
Looking in Enterprise/PageCache/etc/config.xml
The adminhtml event "catalogrule_after_apply" trigger "cleanCache()" which delete my FPC. By removing this event my FPC is not deleted after I update a product from the admin. Only the corresponding cache are correctly deleted.
Still have the issue, for new order that invalidate my whole FPC.
