Tries to guess if the content is dynamic or not.
"Since origin servers do not always provide explicit expiration times, HTTP caches typically
assign heuristic expiration times, employing algorithms that use other header values (such as the
Last-Modified time) to estimate a plausible expiration time".
The current implementation considers as dynamic content everything except responses with a
Last-Modified header with a date older than 10 minutes or with an Expires header
specifying expiration in more than 10 minutes.
