NAME
       HTTP::Proxy::HeaderFilter::simple - A class for creating simple filters

SYNOPSIS
	   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 );

DESCRIPTION
       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.

   Constructor calling convention
       The constructor is called with a single code reference.	The code
       reference must conform to the standard filter() signature for header
       filters:

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

       This code reference is used for the filter() method.

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()
	   Initalise 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.
