NAME

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

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 entire 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.
