ASP.NET AJAX Query response leakage

Hi All,

So I have a site using Windows Authentication and an Application Pool using a specific user account for access.

On my page it uses a JavaScript AJAX query to a code behind C# page which spits back data to JavaScript which puts it on the page.

Sometimes (more then exception than the rule) it will spit out results from another users query instead of mine or vice versa.

I am wondering if anyone has experienced this before and what be causing it.

Going to need to see the code but my first guess is somehow this is using a global variable and not considering the web session id...

Can you write some detail about how data is processed? may be some things from cache is picked or may be from a database table.

@tr57285 - Have you tried monitoring your client traffic using the built-in browser tools for IE, Chrome, FireFox?

You might be able to trace down the source of leak by capturing the browser traffic.

If that doesn't work, try the Fiddler web browser debugging proxy - http://www.telerik.com/fiddler

Open your browser console and take a look at the request that is being sent to the server.

Look at the request headers and data
Look at the response.

This is the first step.

Second - if your C# service is responding to a GET - type the URL (get it from the console debug above) and see what comes back.
If a post - setup a dummy form with the data and post that - repeat to see what is happening.

If the above tests result in the problem then there is something wrong with your server code and you need to look at how you are processing your requests.

If you get 0 failures - then ?
