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,
21       and you'll get the adequate filter.
22
23   Constructor calling convention
24       The constructor is called with a single code reference.  The code
25       reference must conform to the standard "filter()" signature for header
26       filters:
27
28           sub filter { my ( $self, $headers, $message) = @_; ... }
29
30       This code reference is used for the "filter()" method.
31

METHODS

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