At present I'm having to set cache-control: max-age header at 61 seconds in order to cache. There is a threshold set in squid.conf limiting caching of objects which can not be revalidated (no cache validator in the response header) and which expires quickly. minimum_expiry_time or something like that. Fixing the server to provide and support cache validators is the better option however. A cache validator is Last-Modified or ETag, and is used by If-Modified-Since or If-None-Match request headers to validate the freshness of the cached copy. Regards Henrik
