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.)

SEE ALSO¶
