Alert User If Navigating Out of SSO-protected Sites

[Jack HU]

I have casified three web applications successfully.   I want to alert a user if he/she types a different url directly and goes to another site, or I have a few links which will go to another site which does not require sso authentication.   But before a page goes out of SSO-protected site, how can I alert a user that it is going to another site not protected by SSO.  If he continues, then the sso session will be invalidated (that means it will log the user out; and if he comes back, it would require a login again).   How can it be implemented?

Any advice?   Do appreciate your help on this.
