My session variable is not preserving same value through out pages, It is working fine in local but not in server. I have a page with three different modules (I am including) and I am using session to store values in sessions. I am using Jquery, where user clicks on link, a pop-up form appears and user have to fill some information like email, phone, after filling a code will send on both email and cell. Now, When I prints, its showing perfectly on that page as well as in that pop-up windows in local but when I check server it prints different values both both.
