Cross Domain Data Post

Question

Hi Friends,

 

I have a doubt & need solution for the below issue;

 

Cross Domain Data Post:

We have internal and external application for our portal.

 

Thru  internal application users are enter all member related information and put it in our local db. Once the data successfully saved then its redirect to another application( cross domain).

Where the system will ask all the same information that was already available/entered.

 

Instead of getting the information again from member, we have to populate those information from DB/Service to UI. These we need to do it in back ground with out displaying it to user. we have to submit all information once it populate to all page

 

Please assist me, how to pass  one page data to another page & populate those info in page control via crossdomain.
