I have some logic I want to run on the server-side. It's implemented in Javascript, and I'd like to use it to generate and emit JSON, to allow a REST-api for a web app I'm producing.

Development is on Windows7 and IIS. I know IIS still supports ASP, which can be implemented in Javascript.

Is it possible for an ASP classic page to emit JSON?

Yes, no problem. It's possible to use the well-known json2.js from json within a Javascript-based "classic ASP" page.

Per ejemplo:

<%@ language="Javascript" %>

<script language="Javascript" runat="server" src='json2.js'></script>
<script language="Javascript" runat="server">

(function() {

    scriptEngineInfo = function () {
        var s = {
            engine : ScriptEngine(),
            version: {
                major: ScriptEngineMajorVersion(),
                minor:ScriptEngineMinorVersion()
            },
            build: ScriptEngineBuildVersion()
        };
        return s;
    }

}());


var x = scriptEngineInfo();
var d = new Date();
x.Timestamp = d.valueOf();

Response.Write (JSON.stringify(x));

</script>

This is a basic example of how to create a .json file with classic ASP.

<%
Response.ContentType = "application/json"
Response.Write("{ ""responseCode"": ""success"", ""accountNumber"": ""78527511"", ""ID_Code"": ""654321"", ""version"": ""1""}")
%>

having as a result:

{
  "responseCode": "success", 
  "accountNumber": "78527511", 
  "ID_Code": "654321",  
  "version": "1"
}

Here is a great article on it which includes some example code: http://www.webdevbros/2007/04/26/generate-json-from-asp-datatypes/
Its best to put you data in a properly structured array and this code will show you have to take an array and output JSON formatted text.
