Expired ssl warning
is there any irule to disabled the ssl warning from client side? i mean if the certificate is expired then remove the warning and open the website.
No, it is the client (browser) which looks at the certificate and shows a warning if that option isn't disabled (which is almost not possible anymore).
If the server could influence that, the whole TLS/SSL trust system would be broken.
So just update the certificate, which is a good thing to do anyway.
