Description

Hi there,
I've been playing around with the Caching HttpClient a bit. It works nicely, but one thing really is of concern for me:

When dealing with lots of identical requests, the cacheDir quickly gets filled up with copies of all the same files.

I understand that technically these responses have not been invalidated due to the new request, but from my perspective it would make sense to invalidate them because they are technically superseded by the new response. Or even better, use the same file for all responses, as that would save IO on high-throughput systems.

Thanks in advance for your time and keep up the good work!
