I have just finished an IE Hosted UserControl named MyUserControl, which can
automatically download from IIS site if I assigned the URL to
http://MyComputer/MyFolder/index.htm.  However, if I assigned the URL to
http://www.MyCompany.com/MyFolder/index.htm or
http://localhost/MyFolder/index.htm, IE will not automatically download the
MyUserControl from iis.  Where three of MyComputer, www.MyCompany.com, and
localhost means same machine.

Why?  They are same machine, why only a shortly computer name can download,
but long site name and localhost cannot download?  Because of security
issue?

Thanks.
