# Browser Caching: http://code.google.com/speed/page-speed/docs/caching.html#LeverageBrowserCaching
#
# Google recommends specifying the following for all cacheable resources:
#
# 1. Expires or Cache-Control max-age
#
# Set Expires to a minimum of one month, and preferably up to one year, in the future. (We
# prefer Expires over Cache-Control: max-age because it is is more widely supported.) Do not
# set it to more than one year in the future, as that violates the RFC guidelines.
#
# 2. Last-Modified or ETag
#
# Set the Last-Modified date to the last time the resource was changed. If the Last-Modified
# date is sufficiently far enough in the past, chances are the browser won't refetch it.
#
# Per Google: "it is redundant to specify both Expires and Cache-Control: max-age, or to specify
# both Last-Modified and ETag."
