    This module is EXPERIMENTAL. I use it in development and it works
    swimmingly for me, but it is completely untested in production
    scenarios.

METHODS

 build_headers_from_env

    Supplement the headers-building logic from Plack::App::Proxy to
    maintain the complete list of proxies in X-Forwarded-For and to set the
    following headers if they are not already set: X-Forwarded-Proto to the
    value of psgi.url_scheme, X-Real-IP to the value of REMOTE_ADDR, and
    Host to the host and port number of a URI (if given).

    This is called internally.

 switching_response_headers

    Like response_headers from Plack::App::Proxy but doesn't filter the
    "Connection" header nor the headers listed by the "Connection" header.

=head1 METHODS

=head2 build_headers_from_env

Supplement the headers-building logic from L<Plack::App::Proxy> to maintain
the complete list of proxies in C<X-Forwarded-For> and to set the following
headers if they are not already set: C<X-Forwarded-Proto> to the value of
C<psgi.url_scheme>, C<X-Real-IP> to the value of C<REMOTE_ADDR>, and C<Host>
to the host and port number of a URI (if given).

This is called internally.

=head2 switching_response_headers

Like C<response_headers> from L<Plack::App::Proxy> but doesn't filter the
"Connection" header nor the headers listed by the "Connection" header.
