Indy HTTP post error to Delphi CGI ISAPI app

Hello,

When I attempt to do an HTTP post from a Delphi desktop app with the Indy
HTTP client to a Delphi ISAPI CGI (exe) app, I receive a 401 access denied
error.  Only from the desktop app do I get this, from a browser it works
fine.  Also, there is no problem using the HTTP component to post to ASP
pages, only the CGI exe.

Using Indy 9, Delphi 7 enterprise.

Any ideas or thoughts are greatly appreciated!

Thanks in advance,
Craig
