irule to redirect based on HTTP header

Hi guys,

I am not a professional coder and Im trying to find and start to develop a irule to redirect our HTTP request to a especific pool, but cant find nothing similar to start a new one.

Our LTM receives from the browser an HTTP header with this information:

VALIDADOR_USER: 10\r\n (I take it just equals from the wireshark, the number is random 10-27)

I want to try a code that will take it number from VALIDADOR_USER and load balance to 4 diffent pools.

i.e.:

if VALIDADOR_USER: 10 or 11 or 12 or 15 > pool_1

if VALIDADOR_USER: 16 or 17 or 18 or 19 > pool_2

if VALIDADOR_USER: 20 or 21 or 22 or 23 > pool_3

if VALIDADOR_USER: 24 or 25 or 26 or 27 > pool_4

I wonder if its possible to do something based on comparing this values through datagroups and if it matches the LB will be trigged..

Please, can you guys give me a help ?

Regards,

Cadu.
