Redirect to pool member based on URI with persistence

Careful you do not direct them to the logon page all the time and i would look at using switch instead of if elseif but put an if as a top level trigger, only do this if the URI starts with "/ap" then just strip the "/apx" from the uri.

Think the following should do the job:

 Allow server selection via uri
when HTTP_REQUEST {
    set uri [string tolower [HTTP::uri]]
    if {$uri eq "/"} {
        HTTP::uri "/wfc/logon"
    } elseif {$uri starts_with "/ap"} {
        switch -glob $uri {
            "/ap1" {
                pool Kronos member 192.168.1.121 80
                HTTP::uri [string map {"/ap1" ""} $uri]
            }
            "/ap2" {
                pool Kronos member 192.168.1.122 80
                HTTP::uri [string map {"/ap2" ""} $uri]
            }
            "/ap3" {
                pool Kronos member 192.168.1.123 80
                HTTP::uri [string map {"/ap3" ""} $uri]
            }
        }
    }
}
