# Static file handler for Rails < 2.3. This handler is only provided
# as a convenience for developers. Performance-minded deployments should
# use nginx (or similar) for serving static files.
#
# This supports page caching directly and will try to resolve a
# request in the following order:
#
# * If the requested exact PATH_INFO exists as a file then serve it.
# * If it exists at PATH_INFO+rest_operator+".html" exists
# then serve that.
#
# This means that if you are using page caching it will actually work
# with Unicorn and you should see a decent speed boost (but not as
# fast as if you use a static server like nginx).
