NAME

Top

HTTP::Proxy::Selective - Simple HTTP Proxy which serves some paths from locations on local disk.

SYNOPSIS

Top

    use HTTP::Proxy;
    use HTTP::Proxy::Selective;
    my $filter = {
        'www.example.com' => {
            'css/' => '/home/t0m/example/css',
            'js'   => '/home/t0m/example/js',
        },
    };
    my $proxy = HTTP::Proxy->new();
    $proxy->push_filter( 
        method => 'GET, HEAD',
        request => HTTP::Proxy::Selective->new($filter)
    );
    $proxy->start;

See the script shipped in the distribution selective_proxy for a slightly more complex example of use.

DESCRIPTION

Top

HTTP::Proxy::Selective acts as a filter for HTTP::Proxy. You pass it a filter data structure when you create it (as per the example above), and any URLs requested through the proxy which match the filter are served from the path on local disk specified by the configuration.

Note that if a file is a filtered path is not found on local disk, then a 404 error is generated, it is not sent to the origin server.

METHODS

Top

new $filter

Constructs an instance (validating the filter etc as it does so).

filter $self, $headers, $message

Method which performs the filtering, called by HTTP::Proxy.

SEE ALSO
