xmlhttp.send DataToSend
Response.Write(xmlhttp.responseText)
I'm not an expert in old-school ASP, but that looks suspect to me. I would expect the call to be asynchronous, so you are attempting to write out the response before you've received it. A better bet would be to use jQuery to call the site for you. I have an article
here[
^] that demonstrates how to do this in jQuery.
