Thanks I will try that tomorrow and let you know.

 

I think I may need to add the following to get an alternative client profile to ask for the client cert though.  Is that right?

.......

        # Redirect to a special URI that will prompt for a client certificate
        HTTP::redirect "/require-cert$httpUri"

    SSL::session invalidate
    SSL::authenticate always
    SSL::authenticate depth 9
    SSL::cert mode require
    set cmd "SSL::profile /Common/ClientSSL-RequireCert-Profile"
    SSL::renegotiate

return

........

Hi.

I did try this method, but got hit with a few little snags that I think are telling me I can't run these HTTP commands in the CLIENTSSL_CLIENTCERT event.  Although the last line suggests I have not got the syntax right for the variable, which I could fix it is the first 3 lines that suggest I can't make this work because they need to be in the HTTP_REQUEST event, is that correct?

 

 

 

I am going to try and fire off a subroutine(Proc) to re-initiate the the ssl negotiation against  different client SSL profile and then execute another Irule to trigger the CLIENT_SSL event and subsequent HHTP_REQUEST event which all seems very complicated so open to other simpler suggestions like this previous one from susan789wolf that showed real promise in the simpler logic
