Using HTTP::collect from event HTTP_REQUEST_SEND

So I have (temporarily) given up on the HTTP::collect in HTTP_REQUEST_SEND functionality pending our account team poking the developers for a response, however I tried to setup 2 VIPs, (a frontend VIP using ASM, and a backend VIP using my iRule), and have the frontend invoke the backend one by placing the backend VIP IP in a pool, however it doesn't work :-(.

 

 

Had a quick word with our local f5 guys, and invoking the backend VIP from the frontend by using an iRule with the command ;-

 

virtual

 

works a treat. Thanks local team!!
