Stream Profile ::: header / data manipulation

I want to implement it in live environment , where BigIp LTM 10.2.X should rewrite location header in first response it receive from the server .

with http profile, stream profile/irule does not rewrite http header. you may check HTTP::header replace Location command instead.

Rewrite HTTP Redirect Hostname

I found the below irule from dev site but facing trouble in understanding the function , how it is working .

anyway, if you would like, you may start from askf5.
