HTTP

...

The following setting is pretty important.

This one defines a global variable whose function is to indicate whether specific HTTP headers
are necessary to properly cache an object. As it turns out, they are necessary.

From Leif H: "PLEASE, do no set this to 0 unless you own both the cache and the origin. In “0”, it allows everything to be cached, unless it’s explicitly denied. This is a direct violation of RFC2616, and will in forward proxy, will certainty break things where more than one user is behind the cache. Set it to “1”, which can still break for poorly behaved web sites (e.g. amazon.com used to break with it set to “1”, which is why we set it to “2”."

My mistake...I had no idea this violated an RFC. This has been duly updated.

CONFIG proxy.config.http.cache.required_headers INT 1

HTTP RAM Cache

While the default ATS options for this may be optimal under heavy load,
I found using the simpler LRU algorithm much faster and more useful.
