Stuff in the 'static' dir are normal Zope3 resources. They set the
Last-Modified headers automatically based on the file's modification
time and know how to deal with a browser's If-Modified-Since request
. They also tell the browser that a file resource has a cache
lifetime of one day (86400 s) via the Cache-Control header. This
value isn't easily customized.
