NAME

HTTP::Proxy::BodyFilter::complete - A filter that passes on a complete body or nothing

CONTENTS

SYNOPSIS



    use HTTP::Proxy;
    use HTTP::Proxy::BodyFilter::simple;
    use HTTP::Proxy::BodyFilter::complete;

    my $proxy = HTTP::Proxy->new;

    # pass the complete response body to our filter (in one pass)
    $proxy->push_filter(
        mime => text/html,
        response => HTTP::Proxy::BodyFilter::complete->new,
        response => HTTP::Proxy::BodyFilter::simple->new(
            sub {
                my ( $self, $dataref, $message, $protocol, $buffer ) = @_;
                # some complex processing that needs
                # the whole response body
            }
        );
    );

    $proxy->start;



DESCRIPTION

The HTTP::Proxy::BodyFilter::complete filter will ensure that the next filter in the filter chain will only receive complete message bodies (either request or response).

It will store the chunks of data as they arrive, only to pass the <B>entireB> message body after the whole message has been received by the proxy.

Subsequent filters is the chain will receive the whole body as a big piece of data.

CAVEAT EMPTOR

This consumes memory and time.

Use with caution, otherwise your client will timeout, or your proxy will run out of memory.

Also note that all filters after complete are still called when the proxy receives data: they just receive empty data. They will receive the complete data when the filter chain is called for the very last time (the $buffer parameter is undef). (See the documentation of HTTP::Proxy::BodyFilter for details about the $buffer parameter.)

METHOD

This filter defines two methods, called automatically:
filter() Stores the incoming data in memory until the last moment and passes empty data to the subsequent filters in the chain. They will receive the full body during the last round of filter calls.
will_modify() This method returns a false value, thus indicating to the system that it will not modify data passing through.
