Let's say I want to share cached nodes with a common taxonomy term between users which share the same taxonomy term. Is this possible ? I want to share cached pages between users with the same taxonomy terms.
My approach so far is to find the requested URL (current_path()) inhook_authcache_key_properties_alter. If it is a node then compare its taxonomy terms with the user's taxonomy terms - this will involve querying the database- . If the taxonomy terms are the same then it will add the taxonomy term id to the $properties['roles'] array to generate a special key that later will be used by users with the same taxonomy term.

znerol commentedThis probably is not obvious from the documentation, but the cache key must not vary per path. The only safe thing to do in this situation is to unconditionally add the user-terms to the key properties. As a result a different key will be generated for each combination of taxonomy terms (and roles).

znerol commentedAttached is a patch with docs update. I tried to phrase it in a generic way but I'm not sure whether it is clear enough.

angel.angelio commentedIMO, I'd add @see authcache_builtin_cacheinc_retrieve_cache_page
So if the key does not change that often - I mean a 1 or 2 times per session- it might be "OK" to do it.

znerol commentedFrankly I'm not quite sure.
Comment #6
znerol commentedThis patch should be included into a release regardless of the open question.
