CirrusThanks, Kai & Mo. Any chance that better TLS support is going to show up in an upcoming update of the iRule editor? I can certainly use Fiddler to proxy it, but it does seem silly.
when using the cipher string you provided, the cipher used by default clientssl profile are below, doesn't contain TLS1.0. so it might be the cause. you could capture ssl session btw iRule Editor and the bigip to find out more info.
