Hello, I was able to get data from using

use LWP::UserAgent;
  $ua = LWP::UserAgent->new;
  $req = HTTP::Request->new(GET => 'http://www.linpro.no/secret/');
  $req->authorization_basic('aas', 'mypassword');
  print $ua->request($req)->as_string;

however, how do you access the orignal site that I want go to instead of me retrival data from the site?

In essence you don't. Because the authentication has been granted to your CGI script, not to the user.

The short answer is "You can't"

The longer answer discusses the risky username:password syntax and points out that its probably not a good idea to try to use it.

The only way the CGI could provide the user with access to the data would be to act as a proxy (fetching data from the site, rewriting links et al to pass through the CGI and then passing it on to the user)
