Fix caching support for bbPress

[raamdev]

As of v140520-RC, Quick Cache caches pages related to bbPress, but does not purge cache files related to bbPress when certain events take place (such as the creation of a new Forum).

Quick Cache needs to be updated to properly support bbPress.

Just thinking this through with you...

A new bbPress Forum is a new Post with the Custom Post Type: forum; so creating a new Post (of any kind) could somehow warrant a cache purge maybe?

Hmm, it seems to me that in practice, if I create a new Forum I will most likely just clear the cache manually. I think for most sites creating a new Forum is something that is generally done during the initial site configuration, or during a larger restructuring of the site/community.

unfortunately when a new reply posted in bbpress, auto-purging doesn't run and only shown to logged in users. how can i fix it? or how can i bring out bbpress from quick cache?

That makes me think they are allowing anonymous forum submissions; i.e. from users who are not logged into the site. The only way I know to combat this issue, is for us to try to pick up this scenario in the is_like_logged_in_user() method.

@jaswsinc Thanks for your thoughts! I left a reply on the original forum post asking if they're allowing submissions from users who are not logged in.

That said, if someone is logged in and posts a new reply, does that trigger a purge of the cache for that topic? It should, otherwise visitors (who are not logged in) wouldn't see the new reply from the logged-in user.

I haven't looked at the code yet to check this, but I'm noting my thoughts here for when I come back to this.

Punting this to the Future Release milestone.

If user-specific caching is off, then none of this is cached for those logged-in users. The public facing version of the forum topic will remain cached and only show topics/replies since it was last cached.

If user-specific caching is on, and a user does a POST of any kind, it wipes the cache for that user.

I agree, there is more work to be done to get this working perfectly w/ bbPress.
