Hi Atith,
Is this correct understanding? Each app should back to different page.
App A logoff -> Redirect to the page App A logon
App B logoff -> Redirect to the page App B logon
App C logoff -> Redirect to the page App C logon
I believe most of customers have company home page and users can select a business application from the web page which haa the link for App A,B and C. So I would set redirect to the business application link home page after log off.
Most of large customers setup single sign on and do not use basic authentication. In that case, logon screen does not come up.
