So basically I followed these instructions to forward HTTP to HTTPS (Method #2) just changing the error code. Trying to get into a SharePoint 2007 site and I'm using IIS V6.0, Windows Server 2003 R2.
The problem is that (and has been even before changing the error code) is that when I type in the HTTP address I get prompted for a username and password...I type it in...THEN I get another prompt for the HTTPS site, and it takes me there. It did this before I made the error code change, and I'm trying to avoid the double prompt.
Any way to do this? Thanks!
