[squid-users] Cache refresh?

[John Crossman]

Is it possible to refresh a single page within the Squid page cache with a certain 
HTTP query args? 
For example, 
//resource-10-12?squid-refresh=true"http://<host>/<path>/resource-10-12?squid-refresh=true
 
This would flush the cache with regards to the 1 - N page components associated with 
the URL. 
Thanks 
J.
