Rails - Apr 2005 - Problems when using sweepers with postbacks

I''m using a cache sweeper class [1] to take care of some pretty complex
sweeping. However, there is a problem with the current implementation.  
Namely, the sweeper gets called only when an action named in  
cache_sweeper is called using GET. As many methods where sweeper would  
be useful are using postback to send the form to the same action, this  
causes the cache to get swept when the edit form is loaded, not when  
the actual editing in the db is happening.

My idea to solve this would be to accept an array as an item in the  
:only parameter array. It would then consist of the name of the action  
+ the method that should invoke the sweeper. That way the developer  
could select if the sweeper gets called on :get, :post or perhaps both.

I don''t know, maybe there already exists a solution for this. However,
all that I can tell at the moment is that when posting a postback form,  
the sweeper is not called.

Forget this, I was too eager to hit the send button.
