additionally... i've set this line for images (same goes for jpgs and gifs) to send them out form cache for a long time whatever happens. Now i get lots of TCP_MEM_HIT and TCP_IMS_HIT (on browser refresh) on this images but i still get's lots of http requests on this images on the application server. Is squid looking for modifications or something even if i it's a HIT? Is there any way to get around this? Sorry for asking so dumb questions but i guess i don't get the whole party right yet. Thanks, Frank
