Backgroundrb devel - Feb 2007 - accessing controller methods from backgreoundrb

Hi all,

I am trying to use backgroundrb to cache a set of controller actions 
that are quite processor expensive (there is some pretty heavy xml 
processing going on). In my rails app I have page caching set up to 
observe the appropriate controllers and models and all works well. 
However when model changes occur in a backgroundrb process the cache 
sweeper isn''t notified of the changes (and consequently the cache
isn''t
updated).  I assume this is because backgroundrb doesn''t have access to
the controller and view layers?

Is it possible to trigger the normal rails cache sweepers from 
backgroundrb somehow, or, is it possible to gain access to controller 
methods so that I can use render_to_string and save the output of that 
action to a file and create the cached files manually? Either option 
should get me back on track.

A final note - the rails application I''m working on needs to be hosted 
on a windows machine, so I''m stuck using the earlier version of 
backgroundrb for the time being.

thanks,

Dan
