Custom Response Upon Denial with iRule.

Hi,

I understood that you need to send a response in L7.

In my humble opinion, you did a good job.

So, if you aren't receiving the message, your connection may be being dropped before being established.

Could you check your ciphers in SSL client profile?

Anyway, let me do it a little diferent. Respectfully,

when HTTP_REQUEST {
    if { not ([SSL::cipher version] starts_with "TLSv1.") } {
        HTTP::respond 200 content {
            Maintenance page
             **********CUSTOM DENIAL MESSAGE HERE.**********
             } Content-Type text/html Connection close
    }
}
