httpget user/passwd Problem

[GlaucoUri]

HTTPget is simply wonderfull, but i must use an authenticated http connection.

I've searched for something like
HTTPget -u username -P password http://www.mysite.com

I've tryed the url-encapsulated but it don't Work:
HTTPget http://name:password@www.mysite.com


is possible to add username and password ?

Thank You
