Question

Multiple Classic ASP SessionID's when using both AJAX and standard HTML POST requests.

Answer 1

A:

I think there might be something else going here.

I threw together a quick example that I think is doing what you're describing and the sessions appear to be behaving.

<%@ LANGUAGE=VBSCRIPT %>
<% if Request.Form("curid") = "" then %>
<html>
    <head>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.3/prototype.js"&gt;&lt;/script&gt;

        <script type="text/javascript">
            Event.observe(window, 'load', function() {
                Event.observe($('sessiontest'), 'click', function(event) {
                    Event.stop(event);

                    new Ajax.Request( 'test.asp', {
                        method:  'POST',
                        parameters:  {'curid':  $('curid').value},
                        onSuccess:  function(response) {
                            window.location = 'test.asp';
                        },
                        onFailure:  function() {
                            alert('FAIL!');
                        }
                    });
                });
            });
        </script>
    </head>
    <body>
            <p><input type="text" id="curid" value="<%=Session("curid")%>" /></p>
            <p><a href="#" id="sessiontest">Save ID to Session</a></p>
    </body>
</html>
<% 
else
    Session("curid") = Request.Form("curid")
    Response.write "I was called via POST"
end if 
%>

I'm also Windows w/ FF 3.0.6.

A:

Ben,

I'm pretty certain, (while I have not confirmed for sure) that double asp sessions are the result of a worker process (application pool) assigned to more than 1 virtual host on the same server. Any chance that is the case in your environment?

I stumbled across this page as I am just about ready to debug and deploy a classic asp ajax implementation whereas this is a concern I wanted to investigate before even doing so.

Also default ASP Session behavior has changed throughout the generations of windows servers (however not sure about how it works in XP/Vista implements of IIS).

My post is a little bit dated by two months, did you get this situation resolved? And curious what Server environment/IIS you are testing/using with your situation.
