I am using aspjson from aspjson.com to parse and write json in classic ASP to interact with Authorize.net. I have it working, but have something wrong. The response from the server is being written to the browser along with being inserted in my form field (as expected). How do I prevent this?
The include i'm using can be found at http://www.aspjson.com/
I think it has something to do with the response type, but I don't know how to set it correctly. I've tried xmlhttp.responseType = "json" but it prevented my token from populating my form element. I also tried setting my variable to xmlhttp.response, but it didn't seem to make a difference.

The problem is the JSON response is the first thing being written to the browser above the <HTML> tag. The variable vAnswer contains the complete JSON response from the server which I am receiving successfully. It looks like this
{"token":"1Zxb060yfEUSZpUT6X0PPv...superLongButWorkingToken...Mvrbg.2GgexrHg74XQ","messages":{"resultCode":"Ok","message":[{"code":"I00001","text":"Successful."}]}}
The response is parsed and the Token I need is contained in the variable vToken which is being successfully populated in my form field.
vAnswerthat is added orqJSON.JSONOutput()?<html>tag. The issue must come fromaspjson.asp.
