The regex on that line is not correct. The "http://*."; part requires 0 or more '/' characters before the "application.net" domain name. It *does not* match sub-domain segments. Also Squid does not need a trailing .* pattern, that is implicit. I think the pattern you were trying to achieve is: ^http://(.*\.)?applicationurl\.net(\..*)?/ Also be aware that refresh_pattern does not force those parameters on any URL. It is simpy providing default values *if* (and only if) the response for matching URLs does not contain the relevant Cache-Control settings. If the server provides caching values, those will be used instead. > Is there a way to overcome this issue?

From your description it sounds like the application updates its content more often than each 10mins. Take the URL from your access.log and paste it into the tool at http://redbot.org. It will tell what cacheability behaviour is expected. The 10-15 second delay is not something Squid can do much about, if the server takes that long to generate a reply thats what it takes.
