  1. POASP.Net: IHttpAsyncHandler and IRequiresSessionState not working
    text
    copied!<p>I have implemented an IHttpAsyncHandler. I am making about 5 different AJAX calls from a webpage that has widgets to that handler. </p> <p>One of those widgets takes about 15 seconds to load(because of a large database query) the others should all load in under a second. The handler is responding in a synchronous manner.</p> <p>I am getting very inconsistent results. The ProcessRequest method is using Session and other class level variables. <strong>Could that be causing different requests to use the same thread instead each there own?</strong> </p> <p>I'm getting this...</p> <p>Request1 ---> response 1 sec<br> Request2 ---> response 14 sec<br> Request3 ---> response 14.5 sec<br> Request4 ---> response 15 sec<br> Request5 ---> response 15.5 sec<br></p> <p>but I'm looking for something more like this...</p> <p>Request1 ---> response 1 sec<br> Request2 ---> response 14 sec<br> Request3 ---> response 1.5 sec<br> Request4 ---> response 2 sec<br> Request5 ---> response 1.5 sec<br></p> <p>Without posting too much code my implementation of the IHttpAsyncHandler methods are pretty standard.</p> <pre><code>private AsyncProcessorDelegate _Delegate; protected delegate void AsyncProcessorDelegate(HttpContext context); IAsyncResult IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData) { _Delegate = new AsyncProcessorDelegate(ProcessRequest); return _Delegate.BeginInvoke(context, cb, extraData); } void IHttpAsyncHandler.EndProcessRequest(IAsyncResult result) { _Delegate.EndInvoke(result); } </code></pre> <p>Putting a debug break point in my IHttpAsyncHandler.BeginProcessRequest method I can see that the method isn't being fired until the last Process is complete.</p> <p>Also my machine.config has this entry... processModel autoConfig="true" with no other properties set.</p> <p>I'm calling the handler like this...<br> $.ajax( { type: "GET", url: "../HTML/HtmlHandler.ashx", cache: true, dataType: "text", data: { html: name }, success: function(html) { //$(function() { //console.log(tabname); //console.log("msg:" + msg); $("#" + name + "holder").html(html); //checkAllLoaded(); ClientHome_init(''); //}); },</p> <pre><code> error: function(XMLHttpRequest, textStatus, errorThrown) { $("#" + name + "holder").html("&lt;span&gt;Error retrieving widget.&lt;/span&gt;"); //console.log("error:" + tabname); //checkAllLoaded(); } } </code></pre> <p><strong>What else do I need to check for?</strong> </p>
