Does JQuery AJAX have a different User Session than a postback to the same website?

Question

Does JQuery AJAX have a different User Session than a postback to the same website?

I am trying to send data to a MVC2 Controller through a Jquery Ajax POST with a querystring on it and then this MVC2 Controller will take the data from querystring and place it into the User's Session. Successfully while debugging I see that the Controller grabs the querystring, sets a session variable and in the immediate windows I can pull up the Session contents again.

Later my users will come along use a different Controller but same domain and I will check for that User's Session information. It appears to be a whole new User Session even though it is the same user and the same domain.

Any ideas why this might be happening would help. Thank you in advance.

Answer 1

Any Ajax posting will be using the same session so you might have a problem in your code? Can you post some of it that is relevant.
