Creating New Session

[mkolias]

I have and ASP.net web form. When I load this page I set a session variable to the ID for that customer. On the web form I have a new window hyperlink button. When I click this button it opens a new window that contains the main page and should assign a session independant of the current seesion in the other open window. Currently when I click the new window and get to the form that allows me to enter new customer information it creates a new session but in the process, the other open window takes on the same session information. How can I maintain two seperate sessions when I click the New Window button and navigate to the new customer page? Currently I assign the default page location to the NavigateURL of the hyperlink button.

Thanks,
Mike
