Answer 1

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).

Answer 2

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.
