http basic auth ?

I am trying to load a document from an URL protected behind a basic HTTP 
auth. I am passing an url like "http://login:pass@host" to HTLoadToFile, 
and for some reason the Auth module doesn't pick up anything and I keep 
getting 'Authorization required' error.

The above syntax works fine for ftp protocol. But for http, should this 
work too? Or I should be parsing it and setting up the credentials myself?
