webapp to webapp

Hi,
we have two separate web application built on spring web flow, lets say app A and app B
user logs in to A and goes to B, on B he will be asked some ques, once he answers them successfully he will come back to A and continue. if he could not answer he will go to error page.

we have two main issue in this..


1. user starts from A, goes to B, once success he will come back to A app. but if user click on back button,. B app is showing error page. is there a way so that we can take user to same page of A APP with all data?


2. user logs in A and we try to take user to B but B app is down, we show user a blank page. is there a way to know if B is up or down, so that we can show proper message.

Hello

Each App (A, B) has its own Flow Control, they are independent, but perhaps you can around this situation using the externalredirect, where you can send some parameters. In the worst case, share some database.
