iRule for directing OWA/OA Traffic

Hey! Total beginner at iRules so hoping someone could point me in the right direction.

In summary what I want to do is the following:

1) If a Mac Outlook app comes in (using webmail.company.com/ews/exchange.asmx) > Send to a pool

2) If a request comes in directly to webmail.company.com > Redirect to a different URL

3) If any other request come in (ex. autodiscover.company.com) > Continue to default VIP behaviour

Since the domain listed is the same for 1+2 (difference is the URI) I want to make sure that if 1 is hit, 2 is not looked at and sent to the wrong place.

So far I have:

when HTTP_REQUEST {
  if {[string tolower [HTTP::uri]] equals "/ews/exchange.asmx"} {
            pool Exchange_2013_proxy_pool 
  } elseif {[string tolower [HTTP::host]] contains "webmail.company.com"} {
        HTTP::redirect "https://site.company.com" 
  }  
 }

Would this work to satisfy the first 2 conditions listed above? What happens when nothing is matched in this irule (ex. condition 3 where autodiscover.company.com is used)? Does it continue on to whatever the default behaviour is for my original VIP?

Any info or tips would be amazing!

    Yes, if the pool isn't changed by the iRule the default pool will be used. You could also try something like this:

    when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] equals "webmail.company.com" } {
        switch -glob [string tolower [HTTP::uri]] {
            "/ews/exchange.asmx" {
                pool Exchange_2013_proxy_pool
            }
            default {
                HTTP::redirect "https://site.company.com"
            }
        }  
    }
}
