Content Switching for URL using iRule and different Pools

I am trying to create a basic iRule to switch content. I am using single Vserver and need to switch content for 2 different Http URL's using 2 different pools with associated backends servers.

 

URL1. "abc.com" URL2. "xyz.com"

 

URL1 needs to use Pool1 and url2 needs to use Pool2.

 

Looking at some of your previous questions, I created the below iRule. Can anyone please confirm if this is accurate or something needs to be changed.

 

when HTTP_REQUEST { switch -glob [string tolower [HTTP::host]] { "abc.com" { pool pool_1} "xyz.xom" { pool pool_2} } }

    How about something like this,

    Create a DataGroup to map "host header names" to Pool mappings. example HOST2POOL_DG

    "abc.com" := "POOL01",

    "xyz.com" := "POOL02",

    when HTTP_REQUEST {
    set pool_select_value [class lookup [string tolower [HTTP::host]] HOST2POOL_DG]
    pool $pool_select_value
}

    or

    simple irule: 
    when HTTP_REQUEST {
        switch [string tolower [HTTP::host]] {        
        "abc.com" { pool POOL01}        
        "xyz.com" { pool POOL02}        
        }
 }
