HTTP Communication Log Example

This section provides a tutorial example of HTTP communication log of a single ASP session created with a Perl LWP testing program.

If you run it with "reg_client.pl > client.out" in a command window, you will get the following in the window:

LWP::UserAgent::new: ()
LWP::UserAgent::request: ()
LWP::UserAgent::simple_request: GET http://localhost/reg_form.asp
