RSS feeds from access restricted site

Hi,I’m trying to get the rss feeds from an access restricted site (When i enter the URL in the browser, I will be prompted for user name and pw. Only after the authentication, the feeds will be displayed in the browser). Can anyone guide me on how to get the feeds programmatically from an access restricted site. For a rss feeds from un-restricted sites, I can read it by creating a xml object and passing the url to the object (xmldoc.load(url)). Can anyone guide me on how to pass the user name and pw and read the feeds?

thanks
