I have a jsp page containing a tree structure with hyperlinks and that jsp page also contains two iframes, one of the iframe contains login information and the other contains the main application jsp pages. The page on the second iframe changes depending on the link clicked from tree. When a user logins on one iframes certain features are added to the second iframe pages. The problem I am facing is that even though the user has logged in one iframe the second iframe does not show the additional features until the second iframe is manually refreshed. I want the second iframe to be refreshed when correct login information is entered in the first iframe i.e. i want the second iframe to be refreshed only once.
