=head1 NAME

HTTP::Throwable::Role::Status::ProxyAuthenticationRequired - 407 Proxy Authentication Required

=head1 VERSION

version 0.024

=head1 DESCRIPTION

This code is similar to 401 (Unauthorized), but indicates that the
client must first authenticate itself with the proxy. The proxy MUST
return a Proxy-Authenticate header field containing a challenge applicable
to the proxy for the requested resource. The client MAY repeat the request
with a suitable Proxy-Authorization header field.

=head1 ATTRIBUTES

=head2 proxy_authenticate

This is a required string or array of strings that will be used to populate
the 'Proxy-Authenticate' header(s) when creating a PSGI response.
