NAME Plack::App::Proxy - proxy requests SYNOPSIS use Plack::Builder; # proxy all requests for /static to 127.0.0.1:80 builder { mount "/static" => Plack::App::Proxy->new(remote => "http://127.0.0.1:80")->to_app; }; # Call from other app my $proxy = Plack::App::Proxy->new->to_app; my $app = sub { my $env = shift; ... $env->{'plack.proxy.url'} = $url; $proxy->($env); }; DESCRIPTION Plack::App::Proxy is a middleware-aware proxy application for Plack. OPTIONS remote Plack::App::Proxy->new(remote => 'http://perl.org')->to_app; Specifies the base remote URL to proxy requests to. builder { mount "/example", Plack::App::Proxy->new(remote => 'http://example.com/app/foo')->to_app; }; This proxies incoming requests for "/example/bar" proxied to "http://example.com/app/foo/bar". preserve_host_header Preserves the original Host header, which is useful when you do reverse proxying to the internal hosts. backend The HTTP backend to use. This dist comes with "LWP" and "AnyEvent::HTTP" backends. "AnyEvent::HTTP" is the default if no backend is specified. MIDDLEWARE CONFIGURATIONS This application is just like a normal PSGI application and is middleware aware, which means you can modify proxy requests (and responses) using Plack middleware stack. It also supports the following special environment variables: plack.proxy.url Overrides the proxy request URL. plack.proxy.remote Overrides the base URL path to proxy to. For example, the following builder code allows you to proxy all GET requests for .png paths to the lolcat image (yes, a silly example) but proxies to the internal host otherwise. my $mw = sub { my $app = shift; sub { my $env = shift; if ($env->{REQUEST_METHOD} eq 'GET' && $env->{PATH_INFO} =~ /\.png$/) { $env->{'plack.proxy.url'} = 'http://lolcat.example.com/lol.png'; } $app->($env); }; }; use Plack::Builder; builder { enable $mw; Plack::App::Proxy->new(remote => 'http://10.0.0.1:8080')->to_app; }; AUTHOR Lee Aylward Masahiro Honma Tatsuhiko Miyagawa Jesse Luehrs LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
