I've developed a print mechanism for an intranet application running over HTTPS. Using javascript and jQuery I create an iframe in the page and populate it with all the dynamic data that should be printed.

The iframe has a source of `/MyController/Print` which just returns a blank dummy page. This is then replaced with the dynamic content. I do this to avoid having the page location be "about:blank" on the print outs and to get a popup about some secure content, some insecure content.

This works great locally, but once it's on the https server I get a domain authentication popup when trying to create the iframe. It's asking for my username and password (even though the main application never does --- it uses the internal network to identify users).

Is there some way to suppress the user/pass popup?
