Calling JavaScript programmers

I'm banging my head against something, hope someone can tell me where I'm going wrong.

I'm trying to use an xmlhttp object to POST some form data, but no matter what I do it sends the data as a multi-part form rather than URLencoding it.

var formData = new FormData();

formData.append("username", "Groucho");
formData.append("accountnum", 123456); // number 123456 is immediately converted to a string "123456"

var request = new XMLHttpRequest();

request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            //var myArr = JSON.parse(this.responseText);
            //myFunction(myArr);
            document.getElementById("id01").innerHTML = this.responseText;
            alert(this.responseText);
        };
    }

request.open("POST", "hello.asp");
request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
request.send(formData);

When print out Response.Form (yes, Classic ASP) it is a multipart form:

------WebKitFormBoundarykSkKTglESpQu7lHa Content-Disposition: form-data; name="username" Groucho ------WebKitFormBoundarykSkKTglESpQu7lHa Content-Disposition: form-data; name="accountnum" 123456 ------WebKitFormBoundarykSkKTglESpQu7lHa-- ------WebKitFormBoundarykSkKTglESpQu7lHaContent-Disposition:form-data;name:= "username"Groucho------WebKitFormBoundarykSkKTglESpQu7lHaContent-Disposition:form-data;name="accountnum"123456------WebKitFormBoundarykSkKTglESpQu7lHa--

Thoughts?

So, (sorry, just had to) after figuring out the right Google search terms it turns out that FormData objects are *always* sent as multipart forms. It would have been nice if this was included in the documentation. #rage
