Redirect multiple CNAME to a pool

Hello, Just want to ask for your thoughts on what would be the quickest way to redirect multiple CNAME for our website to specific pool? For instance, we have cname1.site.com, cname2.site...

Should be something like this?

when HTTP_REQUEST {
 
if { [HTTP::host] eq "cname1.site.com" "cname2.site.com} {
 
pool pool_name
 
}
 
}

It will be easier to manage if you create a datagroup (type string) to hold the CNAMES, and match against the datagroup.
when HTTP_REQUEST { # cname_dg is a datagroup of type string containing matching cnames if { [HTTP::host] equals cname_dg} { pool pool_name } }

  Thanks for pointing that out. I haven't really think of it or if that is even possible. Quick question though, Does the string and value on creating DG needs to match or just adding the cnames as the string would be all good?
  
  Thanks again , Really appreciate it

  You just need the cname as the String: , and leave the value blank.
  
  Oh - and you can match against a datagroup in a local traffic policy as well
