Since you're already using the POST method, you can pass data in the body.

xmlRequest.send("Field1=abc&Field2=def");

You can retrieve the data on the server, e.g. in ASP.NET:

if (Page.Request.Form["Field1"] == "abc") ...

For GET method you can only use the query string for transferring data.

You're sending the request via post, but putting everything in the query string!

Instead, you should send the data as the body of the request (passed to the send method).
