after debugging whole scenario using firebug sure issue regarding cross domain policy. kindly me figure way out of this'

http 302 refers status code having redirection information. may app2 tried login app1 , sent logged in url response.

once app2 receives such response, proably redirection url out of response can extracted , url should hit again app2.
