Title: Adding MaxAge to the Cache-Control header

Adding MaxAge to be 365 days on the Cache-Control header tells the
browser that this resource will not change in 365 days, so it doesn't
have to check with the server for any changes. This has a significant
impact on mobile devices where the 304 round trip latency could be high.
