Description

The Session is on the server side so you need to call the server in order to set or retrieve session variables.

Just post to a controller and set the Session variable there.

Sample

jQuery

$(function () {
    $.post('/SetSession/SetVariable', 
           { key : "TestKey", value : 'Test' }, function (data) 
    {
        alert("Success " + data.success);
    });
});

Mvc Controller

public class SetSessionController : Controller
{
    public ActionResult SetVariable(string key, string value)
    {
        Session[key] = value;

        return this.Json(new { success = true });
    }
}
