Example Web Request : https://sub.example.com?return_url=blabla.other.com
I want to process an incoming web request from istio and forward it to the address below with a 302 redirect.
if return_url contains "other.com"(this is static) , then 302 Redirect to blabla.other.com
blabla.other.com can be dynamic value. it can be abc.other.com, cde.other.com , etc..
