HTTP::Proxy::HeaderFilter::simple3pm

Usage

    use HTTP::Proxy::HeaderFilter::simple;
    # a simple User-Agent filter
    my $filter = HTTP::Proxy::HeaderFilter::simple->new(
        sub { $_[1]->header( User_Agent => 'foobar/1.0' ); }
    );
    $proxy->push_filter( request => $filter );

Overview

HTTP::Proxy::HeaderFilter::simple can create BodyFilter without going through the hassle of creating a full-fledged class. Simply pass a code reference to the "filter()" method of your filter to the constructor, and you'll get the adequate filter.

    sub filter { my ( $self, $headers, $message) = @_; ... }

Methods

This filter "factory" defines the standard HTTP::Proxy::HeaderFilter methods, but those are only, erm, "proxies" to the actual CODE references passed to the constructor. These "proxy" methods are:

filter()

begin()

end()

Two other methods are actually HTTP::Proxy::HeaderFilter::simple methods, and are called automatically:

init()

Initialise the filter instance with the code references passed to the constructor.

can()

Return the actual code reference that will be run, and not the "proxy" methods. If called with any other name than "begin" and "filter", it calls "UNIVERSAL::can()" instead.
