…as the guy who had written it: The URI printed out by line 112 (Fetching/processing…) is the URI that actually will be fetched.
Some additional things that could go wrong:
- The wiki is password protected. If so you might get around the issue by setting your URI to http://user:password@thesite.com
- The server redirects your browser after accessing the URI. I don’t know if perl’s HTTP library handles that.
