HTTP::Proxy::HeaderFilter::standard - An internal filter to respect RFC2616
This is an internal filter used by HTTP::Proxy to enforce behaviour compliant with RFC 2616.
This filter implements a single method that is called automatically:
Enforce RFC 2616-compliant behaviour,
by adding the
X-Forwarded-For: headers (except when the proxy was instructed not to add them),
Max-Forwards: header and removing the hop-by-hop and LWP::UserAgent headers.
Note that the filter will automatically remove the
Accept-Encoding headers if the proxy has at least one HTTP::Proxy::BodyFilter filter.
(This is to ensure that the filters will receive uncompressed data.)

Thanks to Gisle Aas, for directions regarding the handling of the hop-by-hop headers.
