implementing client certificate support

[Sean Conner]

It was thus said that the Great Peter Vernigorov once stated:
> Wouldn’t the rest of that server’s content be also in the same language and

  Why?  Think of a server written with English error messages yet used to
serve up content in Thai.  Most of the servers are written by English
speaking people, but that doesn't mean all users of said software speak
English---my example just turned that on its head.  And it assumes that the
error messages can't be modified to a particular langauge.
