Moving a session between a window and a modal dialog box

When I open a modal dialog from a parent window using a button click, everything works fine in WinXP with IE8. However, in Win7 with IE8, I encounter an issue where the modal dialog takes me to the login screen. Oddly enough, if I enter my credentials, close the dialog, and reopen it, it functions properly.

Upon investigating, I realized that the session information isn't being passed between the parent and child windows. The modal is triggered using the window.open JavaScript function.

I am hesitant to store login credentials in a cookie and then retrieve them in the modal window, as this goes against security best practices. What could be causing this discrepancy between Win7 and WinXP, and is there a way to resolve this issue?

Answer №1

When the session is stored on the server, the browser will recognize the modal dialog as part of the same site, allowing it to access the session details. If you are experiencing issues, it could be due to disabled cookies.

Try displaying the session value on both screens to see if it is null when the modal dialog is first opened.

It is possible that the problem lies with an if(IsPostPostBack) statement in the modal dialog. Feel free to share some code for further assistance.
