What's the easiest way to set the "Expires" HTTP response header when
using WEBrick?
Using the response object passed into do_GET, I think I need to do this.
res['Expires'] = some_string
The question is how to create some_string with a valid value.
For example, what if I what to set it to the current date/time plus one hour.

I found my own answer.
require 'date'
# Get current time in GMT.
t = Time.now.gmtime
# Add one hour.
t += 60*60
# Set "Expires" header to this time, properly formatted.
res['Expires'] = t.strftime("%a, %d %b %Y %H:%M:%S GMT")

As a pointer for others looking to do the same in Rails, we've wrapped
it in a method you can call inside any action:
expires_in 20.minutes
..there's also "expires_now". The method is available in beta gems and
will be a part of the next release.
