Can you check if a web application is already running on another browser tab?
<p>I have a web application written in ASP.NEt/C# and javascript.  It uses session variables.</p>

<p>When I open the application, is there a way to check if the application is running in another tab?</p>

<p>Or do you have any ideas on making session variables unique for each tab?</p>

<p>Any help would be great!</p>

<p>Thanks</p>
