Ok, I know this is also LWP, but can teach something. If you have LWP installed with all its scripts, you have a GET command you can use in your shell, which outputs (dumps) the page content to STDOUT.
This means you can do
open MYHANDLE, "GET http://www.perlmonks.com|";
Also, you can use lynx for the same purpose (this is good because it has some options to remove tags, in case you want).
open MYHANDLE, "lynx -dump http://www.perlmonks.com|";
but, of course, use LWP. If you don't know where to start, look into LWP::Simple
