I was hoping to employ Squid in a classroom situation so that when all students wanted to open the same web page at the same time, only one copy of the page would be downloaded, and all subsequent requests would be served from Squid cache. However I have not been able to persuade either Moz or IE to retrieve typical web pages from Squid cache (they are of course happy to retrieve the same pages from browser cache). Is this your experience in this situation?
