I join Eliezer in begging for pointers to relevant posts or pages.

We already have squid.conf options to drop headers. Folks that want to
focus on saving bandwidth may use them. We can publish the corresponding
configuration excerpts on the wiki.

If those options are not enough, let's add more. If those options slow
Squid down too much, let's discuss optimizations (keeping in mind that
much better optimizations can probably be obtained by preserving header
blobs during forwarding).

However, please do not hard-code policing of messages Squid can grok,
especially in the parser.

Thank you,

Alex.
