Irule to redirect

I have a requirement from a client to set up the follwing loadbalancing:

 

Client need to access this URL:

 

https://xyz.com:10100/xx_Callback/services

 

f5 must load balance to :

 

(Final URL 1) (Final URL 2) (Final URL 3) (Final URL 4)

 

SO the pool has two nodes working on two serivices ( one on 10101 and 10102 and second node on 10103 and 10104)

 

note: the URI changing for node 1 (Callback1)and node 2(Callback)

 

please suggest me the irule for this. I did try something but not working as expected:
