The bit that foxed me was understanding getopts and that the "h" needed a ":"
after it because the option accepts and argument. It'll happily build and run
without this, but segfault when you try to use a "-h" argument.

This definitely and utterly sets a header. It doesn't seem that it's recognised
properly for whatever reason though, e.g here:

- https://developers.google.com/speed/pagespeed/insights/

and here:

- http://highloadtools.com/cachecontrol

But what can you do?

At the moment this just sets a header everywhere for everything being served.
What would be better would be just setting this on certain file types. check-in: a29fb4fb10 user: atomicules tags: trunk
