LWPx::TimedHTTP(3)    User Contributed Perl Documentation   LWPx::TimedHTTP(3)

NAME
       LWPx::TimedHTTP - time the different stages of an HTTP request

SYNOPSIS
	   # do	the work for you
	   use LWP::UserAgent;
	   use LWPx::TimedHTTP qw(:autoinstall);

	   # now just continue as normal
	   my $ua = LWP::UserAgent->new;
	   my $response	= $ua->get("http://thegestalt.org");
	   # ... with optional retrieving of metrics (in seconds)
	   printf  "%f\n", $response->header('Client-Request-Connect-Time');

	   # or	if you don't like magic	going on in the	background
	   use LWP::UserAgent;
	   use LWP::Protocol;
	   use LWPx::TimedHTTP;

	   LWP::Protocol::implementor('http',  'LWPx::TimedHTTP');

	   # or	for https ....
	   LWP::Protocol::implementor('https', 'LWPx::TimedHTTP::https');

	   my $ua = LWP::UserAgent->new;
	   my $response	= $ua->get("http://thegestalt.org");
	   printf  "%f\n", $response->header('Client-Request-Connect-Time');

DESCRIPTION
       This module performs an HTTP request exactly the	same as	LWP does
       normally	except for the fact that it times each stage of	the request
       and then	inserts	the results as header.

       It's useful for debugging where abouts in a connection slow downs are
       occuring.

METRICS
       All times returned are in seconds

   Client-Request-Dns-Time
       The time	it took	to do a	DNS lookup on the host.

       NOTE: The value of this timing is NOT thread safe since it has to
       smuggle the data	back via a global variable.

   Client-Request-Connect-Time
       The time	it took	to connect to the remote server

   Client-Request-Transmit-Time
       The time	it took	to transmit the	request

   Client-Response-Server-Time
       Time it took to respond to the request

   Client-Response-Receive-Time
       Time it took to get the data back

AUTHOR
       Simon Wistow <simon@thegestalt.org>

       Based entirely on work by David Carter -	this module is a little	light
       frobbing	and some packaging of code he posted to	the libwww-perl
       mailing list in response	to one of my questions.

       His code	was, in	turn, based on LWP::Protocol::http by Gisle Aas	which
       is distributed as part of the libwww package.
