Log in only once	Can't Post

Hi there,
See I am building an advanced (i think so:)) forum for myself (something like ubb) and I have one problem.
What do you do so that user has only to log in once in your system. Uhhh...if you don't undersand my english just take a look around. Like on this forum you can log in and then post answers, topics, send message etc.
Or another example can be found on anandtech foums forums.anandtech.com).
Again, I don't ask for the code (though it would help me :)), I just want to undersand how it works (or lets say to check if i am right)

Thank you,
Any help will surely be appreciated

You can set a cookie to store some data on the user's machine, then retrieve the info you need to auto log them in.

Check out CGI::Cookie in the docs.

Here's some code, but you'll need to adjust it for your own use.

Set a cookie...

Code

my $cookie = new CGI::Cookie(-name=>'foo', 
-value=>$cookie_val, 
-expires=>'+6M'); 
 
print "Set-Cookie: $cookie\n";

To verify...

Code

if(my %cookies = fetch CGI::Cookie){ 
if( defined($cookies{'foo'}) ){ 
my $cookie_val = $cookies{'foo'}->value; 
...use your $cookie_val... 
} 
}

The biggest pain will be sorting out your browser text/html header.

Cheers,
Dave.
