Subject: [PATCH] Set Cache-Control headers for certain content on Firebase
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My reasoning is:

* any CSS or JS files
	their name contains their hash — 1 month
* anything under img folder
	might change while keeping name — 1 day
* any image anywhere except img folder
	usually giant photos attached to blog posts, rarely change and if they do, they usually change name as well — 1 month
