[OpenLayers-Users] limit cache buildup on client?

[William Kyngesburye]

I noticed this when I was looking at mapfish, but ultimately it's  
OpenLayers.  As a session in an OL map progresses, cached images build  
up in the browser.  In a tiled map with many layers and fractionalzoom  
on this can get up into the many hundreds quite fast.

I don't know if this adversely affects the browser performance  
(probably depends on how the browser handles cached files).  Is there  
a way to limit the number of images OL caches?  Is it worth worrying  
about?
