We have devoloped a very huge web application for General Motors. The problem we are facing here, whenever we tried to copy either the label or value from the screen (struts with jsp) and paste it in microsoft excel, then try to access the application, the session is getting expired.
This happens only when we copy and paste the content in microsoft excel and not in any other editor like notepad etc.

The following are true
- you have a webapplication with a user session.
- if you select and copy text in your browser, everything is okay
- if you paste it into notepad, you can continue surfing
- if you paste it into excel, your session expires

But it work fines when you could work by using Paste Special, instead of Paste. When you do Paste Special, it gives you a menu of all the types of data on the clipboard. If you choose something simple like plain text or HTML, the problem might go away

how to solve the issue by using paste option instead of paste special?. Why this is not happening in other web application like yahoo, google and etc
