NAME

       HTTP::Proxy::HeaderFilter::standard - An internal filter to respect RFC2616

DESCRIPTION

       This is an internal filter used by HTTP::Proxy to enforce behaviour compliant with RFC
       2616.

METHOD

       This filter implements a single method that is called automatically:

       filter()
           Enforce RFC 2616-compliant behaviour, by adding the "Via:" and "X-Forwarded-For:"
           headers (except when the proxy was instructed not to add them), decrementing the
           "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.)
