Hi Terry,

you may take a look to the iRule below. The rules uses two nested [if] statements to avoid variable usage. 

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] equals "xxsupplier.xx.com" } then { 
        if { [string tolower [HTTP::uri]] starts_with "/supplierguide" } then {  
            HTTP::respond 302 Location "https://xxsupplier.xx.com/supplier_guide.html"
        } else {  
            HTTP::respond 302 Location "https://xxsupplier.xx.com[HTTP::uri]" 
        }
    } else {
         Request for unknown host name.        
    }
}

Cheers, Kai
