Hi,

the cache-blocks are deleted, if a new object is published. Also if a "new user" is created.

It would help, if you introduce an ini-setting like:

IgnoreCacheBlockClasses[]
IgnoreCacheBlockClasses[]=user

and check if the published object is in this array before deleting the cache-blocks.

Maybe the "user-class" is a bad example. e.g. if you have a flash-class and this class never appear in a cache-block it make no sense deleting the cacheblock-cache after create / edit / deleting an object of the flash-class.

Kind regards,
Emil.
