Hi there,

I have 3 sites- Site A,siteB and AW site, which is the authentication site. Site A and SiteB are trusted sites. Let say when a user logs in to site A. he is re-directed back to site A and then does his work. Now when He clicks on Site B, there will be token passed to site B now before he can access the resource, he will be re-directed to AW site where the AW site has to determine is a user is logged or no.

How can I determine that ?

Thanks

- Harjit

You can pass some Hidden Parameters or Appending some data to URL or by using HttpClient for passing Information from one website to another .

Thanks .

If you have Do-It-Yourself security, you're on your own.

If the apps are written to use J2EE's standard container security system, all you need is a single signon security provider such as CAS.
