20.15. Fetching Password-Protected Pages20.15.1. ProblemYou want to use LWP to fetch web pages or submit forms, but the web server requires authentication. 20.15.2. SolutionSet the username and password for a particular realm with the user agent's credentials method: $ua->credentials('http://www.perlcabal.com/cabal_only/', 'Secret Perl Cabal Files', 'username' => 'password'); 20.15.3. DiscussionTo access pages protected by basic authentication, a browser must supply the username and password for the realm of the authentication. The realm is just a string that identifies which username and password the user must supply. The credentials method tells the user agent to send the username and password for a particular realm. A somewhat kludgey solution is to specify URLs with the username and password in them: http://user:password@www.example.com/private/pages/ This is kludgey because links within the returned document do not have your username and password encoded in them. Solutions that rely entirely on URL-encoded usernames and passwords often quickly degenerate into code that wishes it had used credentials to begin with. 20.15.4.
