NAME

6       HTTP::Proxy::HeaderFilter::simple - A class for creating simple filters
7

SYNOPSIS

9           use HTTP::Proxy::HeaderFilter::simple;
10
11           # a simple User-Agent filter
12           my $filter = HTTP::Proxy::HeaderFilter::simple->new(
13               sub { $_[1]->header( User_Agent => 'foobar/1.0' ); }
14           );
15           $proxy->push_filter( request => $filter );
16

DESCRIPTION

18       HTTP::Proxy::HeaderFilter::simple can create BodyFilter without going
19       through the hassle of creating a full-fledged class. Simply pass a code
20       reference to the filter() method of your filter to the constructor, and
21       you'll get the adequate filter.
22
23       Constructor calling convention
24
25       The constructor is called with a single code reference.  The code ref‐
26       erence must conform to the standard filter() signature for header fil‐
27       ters:
28
29           sub filter { my ( $self, $headers, $message) = @_; ... }
30
31       This code reference is used for the filter() method.
32

METHODS

34       This filter "factory" defines the standard HTTP::Proxy::HeaderFilter
35       methods, but those are only, erm, "proxies" to the actual CODE refer‐
36       ences passed to the constructor. These "proxy" methods are:
37
38       filter()
39       begin()
40       end()
41
42       Two other methods are actually HTTP::Proxy::HeaderFilter::simple meth‐
43       ods, and are called automatically:
44
45       init()
46           Initalise the filter instance with the code references passed to
47           the constructor.
48
49       can()
50           Return the actual code reference that will be run, and not the
51           "proxy" methods. If called with any other name than "begin" and
52           "filter", it calls UNIVERSAL::can() instead.
