I have two questions that I didn't see in the FAQ and am hoping some one can provide assistance: 1.) Does Squid support duplicate request detection? More specifically, In a reverse proxy scenario if clientA requests resourceZ and resourceZ is not in the cache, the request for resourceZ is proxied to the back-end server. While the response for resourceZ is being received from the back-end server, another request is received for resourceZ. Will squid proxy this second request for resourceZ to the back-end server or serve the response from the cache as the response is received for clientA? 2.) What is the maximum cached response size that Squid can handle or is there not a hard limit? Thanks in advance for the help.
