Hi All,

I need to write some function to authenticate a visitor using HTTP =
Authentication, matching his login information with another server. =
Here's the idea more clear:

1. A visitor enters www.myserver.com
2. He gets on his screen the user/password HTTP Authentication window =
and tries to login
3. The script should take the provided login information and send it to =
www.anotherserver.com just to check if an authentication success can be =
done using that login information.
4. The script then grants or deny access to the user, based on point 3.

I know how to match the login information using LWP::UserAgent, but i =
can't find the way to force Apache to send a controlled 401 response or =
a way to make the user's browser open the HTTP Authentication window. =
Also, i can't find a way to catch the login information to process it =
and let Perl decide if it is a success login or not.

If it's worth for something, i'm using Apache 2.2 with mod_perl 2.0 and =
Perl 5.8.

Please, if someone can help me understanding how to accomplish this =
task, i'll really appreciate it.

Thank you! :-)

Paco

Paco,

Grab http-sniffer.pl by Tim Meadowcroft so you can see the actual headers=
:

http://schmerg.pwp.blueyonder.co.uk/code.htm

then look over rfc 2617 to decide if you want to use basic or digest auth=
entication.

There are many perl examples for doing this in cgi perl -- google for the=
m.

good luck,
Mark

Hello all,



I am thinking to write a simple (!) script in perl to generate a chart
joining objects. Very much like a flow chart. Has anyone done this before?
Is it possible?

and more objects..





How do we do this?



Thank you.
