Hi,

you can check if the data group exists before searching in it:

 

when HTTP_REQUEST {
     Redirect request to the matching data_group value
    if {[class exists VURL_[string tolower [HTTP::host]]]} {
        set redirect_url [class match -value [string tolower [HTTP::uri]] equals VURL_[string tolower [HTTP::host]]]
        log local0. "Redirecting: [HTTP::host][string tolower [HTTP::uri]] to $redirect_url "
        HTTP::redirect $redirect_url
        }
    }
}
