 <p>basically any ajax routine will do, jQuery is more robust than this modern browser example:</p> <p>server.asp:</p> <pre><code> &lt;%= Application("NFC")%&gt; </code></pre> <p>client.js:</p> <pre><code>function aGet(turl, callback) { var XHRt = new XMLHttpRequest(); XHRt.onload= callback; XHRt.open("GET", turl, true); XHRt.send(""); } aGet("server.asp", function(e){ alert(e.target.responseText); }); </code></pre> <p>once you see how, it's simple, but it's hard to search for. that's got to be about the simplest back-end code ever... kudos on using the under-used yet awesome RAM cache that is the Application object: if used correctly, it can enable great real-time apps dues to the negligible cost of pinging that simple server page.</p>
