Working on the latest SSL3 vulnerability (POODLE) and wondering if you can detect if the browser viewing the website has SSL3 enabled in their settings and if so prompt them with a message.
This is actually sort of backwards. Ideally, if there was a site that ONLY supported TLS, you could test via script whether that is accessible. And if it fails, then you know that user will be impacted when you turn off SSL. Or maybe no one cares to try and phase users over with a week or two of warning and instead just plans to yank SSL and see what happens.
