nginx you can also reload gracefully using the same mechanism. Still. It would be cool if it wasn't needed. I mean - you don't normally restart web servers when a file in the document root changes - why would you still have to do this for changes to SSL certs.

(note: I know that these are two very different things and I know how complicated it is to get all that state correct and to properly re-initialize the SSL context - still, as certificates get more and more short-lived, this would be a cool thing to have)
