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 ,
Yes , it is doable on F5 by two methods LTM Policies or iRule :
First :
> create two pools , and Put " 10.10.10.10 in pool_1" and "10.10.10.11 in Pool_2".

> then , Go to ( Local traffic , Policies ) and follow the below Article , steps to construct you LTM policy :
https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/local-traffic-policies-getting-started-12-1-0/1.html

its quite Long but it is helpful 😀
- you need to perform such below snap shots :
Create two rules in LTM policy :

Do not Forget to Publish your Policy to be able to assign it in virtual servers , find below :

> assign your LTM policy to your virtual server " 172.16.250.100"

> you can do this Task By iRule :

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

> I recommend LTM policy as it is simpe and light on F5 appliance.

I hope this helps you.

Correct answer, just be careful with iRule syntax because putting parenthesis on new lines like that can result in issues - expecially on the elseif statement. Also, pool command is pool <pool_name>

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

I would suggest using LTM policies too, since it uses a configuration template that is better supported during software upgrades, and also typically performs 20% faster.
