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

AUTHOR

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.
