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.
