Interception caching

When the requests from clients are intercepted by a proxy server or are redirected to one or more proxy servers, without configuring the HTTP clients on the client machines or without the knowledge of clients, it's known as interception proxying. As proxying is mostly accompanied by caching, it's known as interception caching. Interception caching is also known by several other names, such as, transparent caching, cache redirection, and so on. Squid can be configured to intercept requests from clients so that we can leverage the benefits of caching without explicitly configuring each one of our clients.
