- Application a.mydomain.com redirects its users to application b.mydomain.com for Account Creation.
- b.mydomain.com creates the account, and redirects the user back to a.mydomain.com with the encrypted Username (+ Timestamp).
- a.mydomain.com reads it and displays on its form.
Cant use it as GET parameter since no logging needs to be done.
Cant set it in cookie as mydomain.com already uses plenty of cookies.
HTTP Post form submission to a.mydomain.com is not possible due to restrictions of the internal development framework.
Can anyone please suggest what should be the ideal approach to send the Encrypted username (+ Timestamp) back to a.mydomain.com
