I just tried Quick Cache and it worked really well on my WP3.3 Multisite Installation.
Now I have only one problem: one of my around 20 sites mustn't be cached but I see on way of deactivating the plugin for this site only. using the URI Patterns does not work and it also says not to put a domain in there.
any idea if this can be made or if there are other caching plugins that you would recommend that support this?
thanks so much!
