Data group "/" definition

I think you're best bet if you want to use a data group would be to put the source host and uri as the name and then the redirect host (& uri) as the value. Then, in your irule you would just use the class command to search the datagroup for the host and uri. Something like this might work. (Note: it will ignore your protocol, so you'd only be checking on

abc.com

http://abc.com

when HTTP_REQUEST {
    set key [string tolower "[HTTP::host][HTTP::uri]"]

    if { [class match $key equals DATA_GROUP_NAME] } {
        HTTP::respond 302 [class match -value $key equals DATA_GROUP_NAME]
        return
    }
}
