static assets served without cache policy leads to suboptimal page speed

[freddyb]

Describe the bug

Static assets (list below) are served without any caching header, which results in the browser re-requesting the files too often.

/fonts/Lora-Bold.woff2
/fonts/Lora-Regular.woff2
/fonts/open-sans-v13-latin-regular.woff2
/js/webfont.js
/js/h.js
/js/postactions.js
/js/localdate.js
/css/fonts.css

Steps to reproduce (if necessary)

Steps to reproduce the behavior:

1. Open Browser (e.g., Firefox) Developer Tools and its network panel
2. Load a writefreely instance
3. Observe response headers

Expected behavior

writefreely server should have responded with a cache header

Application configuration

• Single mode or Multi-user mode? single
• Database? [mysql/sqlite] mysql
• Open registration? [yes/no] no
• Federation enabled? [yes/no] no

Thanks for reporting this, @freddyb! I'm sure we can tweak the Go file server to include the right headers.
