[Xymon] netrc not working

Hi all.? I'm trying to get xymon to log into a device we have and check for a keyword on a certain page.? I know how to check a site for keyword using 'cont', but the device requires a login and I can't seem to get it to work.? It's just an http device, but the http://username:password at 1.2.3.4.com doesn't work, and neither does the 'netrc' file that I found in an old blog post.? Anyone know how to get this to work?
