I think that i actually have another problem. Now i tried to configure iRule where i will tell if HTTP::host contains abc.abc.com use test_pool but it is not working :(

 

I created VS with 443 service port, protocol TCP, Protoco profile tcp, HTTP Profile http, and SSL Profile (Client) SSS.COM

 

i created iRule: when HTTP_REQUEST { if { [HTTP::host] contains "abc.abc.com" } { pool test_pool } }

 

i have same VS with same setup, just instead of forwarding to pool i am using redirect to external URL and that is working fine.

 

Please help and tell me what i doing wrong :(

I don't see any issue with your iRule exept a problem of case sensitive. It's a good practice to add "string tolower" to eliminate case on your host comparison.

If you try with this iRule, do you see the log in /var/log/ltm when a client request abc.abc.com?

when HTTP_REQUEST { 
  if { [string tolower [HTTP::host]] contains "abc.abc.com" } 
  { 
    log local0. "Inside IF, forward to test_pool" 
    pool test_pool 
  } 
}

If yes your problem is somewhere else.
