Abdou76 ,
sure you can do this ,
try this :

when HTTP_REQUEST { 
 if {[HTTP::host] eq "abc.com"}{ 
  pool pool_1
 } elseif {[HTTP::host] eq "xyz.com"}{ 
     pool pool_2
} elseif {[HTTP::host] eq "ghl.com"}{ 
     pool pool_3
     } 
}

Hope it works with you.

Hi Abdou76 ,

you wrote the pool_names wrong inside iRule ,

try to take it "copy" From pool list and "Past" it inside iRule.
Pool name inside irules are Case sensitive , so you must respect lowercase and uppercase letters.
This error related to this.

Try again and inform me.

Okay , this error isn’t relevant to irule itself , there is a mismatching wtih irule’s pool selection and the real pools that you created.
> could you please remove the gap between ( Pool ) and ( Pool_name ) in irule.
I mean ,
line 3 : you write it
pool PREDOM_APP_pool
modify it to
pool PREDOM_APP_pool

or take the script from here directly.

test it again please.

Did it work with you ?
I mean it redirects you correctly and choose the pool correct or not.
Blue squire does not drop traffic it accepts it without issues such as green circle , so it should work with you.

until now , I do not know why the irule does not work with you.

Hi Mohamed_Ahmed_Kansoh
It worked, I created new pools.
Before I used pools that are created with iapp.
Thanks a lot for your help.

Thank you

Hi Abdou76 ,
Great News ,

what is the needed Condition for the third pool , as the selection of pool_1 and pool_2 is based on what is coming in hostname inside Http Requests , so what is the third condition that based on we select the third pool.

Or you need this Pool as a fallback or last resort or make it as a default pool requests directed to if neither pool_1 nor Pool_2 selected.

I am waithing your reply.
