handle ssl and non ssl on the same virtual server and port


We have new(ssl) and legacy(non ssl) client applications, both need to connect to the same virtual server and the same 443 port.

Backend server uses plain http.

So we need LTM to accept both ssl / non ssl connections from clients on the same 443 port of the same virtual server and forward them to the backend application.

We tried irules with no success.

Is there any chance we can manage this situation on the LTM side?


We have BIG-IP Build 0.0.5 Point Release 3

    use iRules to traffic non ssl to redirect https:


    set need_ssl 1


    when HTTP_REQUEST {

    if { ![info exists need_ssl] } {

    HTTP::redirect "https://[HTTP::host][HTTP::uri]"




  • How were the irules configured? Basically, what were they being told to do?


    If the incoming traffic's port 80 (non-SSL) and it can't be redirected to 443, then a port 80 vserver will be needed. So, you're going to end up with two vservers; one using port 80, one using port 443.
