Hi all, I open a borderless popup window from a .aspx page. After updating data in the popup window, i close that window. When i navigate in my parent browser window, few of my session variables are set to nothing. I am sure that this occurs because of the popup window. When i open the window using window.open, my parent window maintains the state. I need replies regarding opening a borderless window and maintaining the state. I took the chromeless.js from this site only. Thanks and Regards, Mani. ---

What kind of session cookies are being generated? How are their expire dates set? Could you pass the session information through a querystring command to the pop-up? How many other cookies are you writing using this… Some code would be helpful: The session code and how you are writing the cookie and what type of cookie is being auto-generated by the server session- and the pop up call script.
