is there an asynchronous way to 'inform' squid if an image changes ? say,
in a scenario where you initially set the Expires time to be in 4 hours,
and prior to that, the image is updated on the server. this question
is in the context of http acceleration mode. it would be nice to say :
purge this image from your cache.

thanks !
