The simplest way to drop re-negotiation in web servers is this (based on an idea by Nelson Bolyard): - start two instances of the web server, one on an alternate port number, with the same contents - the primary instance will accept TLS user authentication, but will not require it - the instance on the alternate port will always require TLS user authentication - neither instance accepts TLS re-negotiations - whenever the primary instance of the web server would request user authentication via TLS do this instead: re-direct to client to the same resource on the alternate port. That's almost entirely automatic. The only thing a webmaster must do is pick a suitable port number for the instance that requires user authentication. The redirects will add some round-tripage. They can be avoided somewhat by re-writing URLs in contents served to point to the right server instance. Ugly, yes, but automatable. Nico --
