irule to redirect more than one url string to a sorry link.

For this I would use a Switch statement

switch [HTTP::uri] {
    "/hello" {
       HTTP::redirect https://oppspame.co.za.html 
    }
    "/bye" {
        HTTP::redirect https://oppspame.co.za.html 
    }
    default {
        pool home.co.za-443
    }      
}
