Hi Joe,
 I have the same problem with XMLHttp. If you are using a redirect which 
sends a 301 or 302 code to the client, you are going to get this error. The 
problem is the Internet Explorer security settings. If 'Access data sources 
across domains' is disabled, then the XMLHttp object will fire an 'Access 
denied' when you call the 'Send' method. This setting is under the 
'Security'(set it to custom, and click teh Custom Level button) tab in the IE 
control panel. The funny thing is, when I put the URL into IE, it works fine.

Hope this helps,
 Elazar
