Help on irule creation.

Hi,

Please try the solution below:

when CLIENT_ACCEPTED {
   set POOL_DEFAULT [LB::server pool]
}

when HTTP_REQUEST {
  if { [HTTP::host] contains "abc.xyz.com" }{
    pool pool_A
  } else {
    pool $POOL_DEFAULT
  }
}

Alternatively, if you have a ton of HOST values and different pools, try using:

when CLIENT_ACCEPTED {
   set POOL_DEFAULT [LB::server pool]
}
when HTTP_REQUEST {
  switch -glob [HTTP::host] {
    "*abc.xyz.com" {
      pool pool_A
    }
    "*def.xyz.com" {
      pool pool_B
    }
    default {
     pool $POOL_DEFAULT
    }
  }
}
