Hi list, I'm running Squid as a reverse proxy to work around a slow webapplication. Basically, I'm caching everything for a *long* time and force-refresh only those pages that need updating, using a script that runs in the background. Some pages have query parameters (e.g. ...?page=2) and I would like to cache those only for a short time. I've tried several variations of the following, but it doesn't seem to work: refresh_pattern \? 30 100% 30 override-expire refresh_pattern . 30240 100% 30240 override-expire I'm beginning to suspect that refresh_pattern ignores query strings, but hopefully I'm wrong. Currently I'm not caching urls with parameters at all (using an urlpath_regex acl), but this is not desirable. Any ideas? With kind regards, Gert Verhoog
