Glad you found it...

Just FYI, if you're posting XML from client to server you shouldn't send it as urlencoded content, but as XML. The proper content tyep for this is text/xml.

One advantage here is that this is raw content - no encoding occurs on this. If you post application-x-urlencoded the client should expect to decode the using URLdecoding which in the case of XML is very inefficient.

>Finally solved the problem. You were right about it being a Header problem. The CGI script apparently was setup to check if the request was coming from a form or not. I was able to fool the server by issueing oXMLHTTP.setRequestHeader("Content-Type", "application/x-www-form-urlencoded") and that did the trick.

>>Not really sure what the problem is on your end. I have a number of browser based applications that are using XMLHTTP on the client with no problems. Your problem may have something to do with the server side not recognizing what you're sending due to missing headers. IIS is very tolerant - other servers are not.

>>>Appreciate the feedback. I've been going over the XML SDK (as much as I can make heads or tails out of it) since I posted this question. I think that my solution might lie in using Execute() with POST instead of Open(). I'm no longer getting any error messages but I'm not getting any Response either. Since this works using a very plain HTML FORM with a POST action I wouldn't think that the CGI script is looking for anything unusual. I think that at this point I just need to figure out what an HTML FORM sends. There is the ACTION= and the various INPUTs name=value pairs. I know about the URL encoding at least about turning the spaces into + and about the & separating the name=value pairs. I've seen various examples that have framming the POSTed data and I've seen the use of ? at the beginning of the data string. I've tried every possible combination that I can think of and either get errors or nothing. Is there any way to trap what an HTML FORM sends out
