The thing is, I am trying to cache comments made by any particular user with a where clause.
Basically, I created a new profile page so that users can have comments left on their page.
So for example, when a user has a new comment left on their page, it will destroy the cache for the query, but ONLY where the 'where' clause is set.
Does that make sense???
So, if the table is called 'profileComments', it won't simply destroy the cache for the entire profileComments table, but just the cached query results for 'SELECT * FROM profileComments WHERE user_id=whatever'
(Crude example, but hope that helps explain)
