If the requested resource is cached in the squid reverse server, the requested resource is returned directly to the client, otherwise the reverse server requests the resource from the web server in the background and then returns the response to the client, while also cached the reply locally for the next requester.
Squid reverses generally only cache bufferable data (such as HTML pages and cookies), while some CGI scripts or dynamic programs such as ASP and JSP do not cache by default. It buffers static pages based on HTTP header tags returned from the web server. There are four most important HTTP header tags:
last-modified: Tells the reverse page when it was modified.
expires: Tells the reverse page when it should be removed from the buffer.
cache-control: Tells the reverse page whether it should be buffered or not.
pragma: Used to contain implementation-specific instructions, the most commonly used is pragma:no-cache
