Okay. For caching the server needs to produce at least a Date: header with current timestamp of when its responding. And a Last-Modified header with timestamp the object was created/modified or at least the same detail as Date. Squid refresh_pattern needs those to estimate future freshness duration for caching. The alternative is to provide an Expires: header. Responses using "no-cache" must provide the above and should also provide an ETag header to improve revalidation accuracy. Note that "no-cache" in HTTP/1.1 is equivalent to "must-revalidate". So Squid-3.2 and later will query with an If-Modified-Since/If-Not-Modified revalidation on every client request. This should not be confused with not caching. > Squid is acting as an reverse proxy. > i cant change the reply headers from the origin server.
