iRule for incoming HTTPS based requests on F5 LTM?

I think your iRule looks good. As long as you're offloading the ssl at the VIP, your iRule should work.

when HTTP_REQUEST { 
    switch -glob [HTTP::uri] { 
        "/mobilinkbioserver*" { 
            pool MobilinkBioServer 
            HTTP::uri [string range [HTTP::uri] [string first "/" [HTTP::uri] 1] end] 
        } 
    } 
}
