To add basic caching headers for different filetypes, add an expires directive to your nginx config file, like this:
|
||
|
|
|
||
|
|
```
|
||
|
|
# Expires map
|
||
|
|
map $sent_http_content_type $expires {
|
||
|
|
default off;
|
||
|
|
text/html epoch;
|
||
|
|
text/css 30d;
|
||
|
|
application/javascript 30d;
|
||
|
|
~image/ 30d;
|
||
|
|
~font max;
|
||
|
|
}
|
||
|
|
|
||
|
|
server {
|
||
|
|
listen 80 default_server;
|
||
|
|
listen [::]:80 default_server;
|
||
|
|
|
||
|
|
expires $expires;
|
||
|
|
...
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
- `off` means no caching headers.
|
||
|
|
- `epoch` is no caching, ask the website itself.
|
||
|
|
- `30d` cache for 30 days.
|
||
|
|
- `max` is the maximum, cache as long as you can.
|
||
|
|
- A `~` in the mimetype indicates a regular expression.
|
||
|
|
|
||
|
|
## Fonts
|
||
|
|
|
||
|
|
It could be that this does not work right away for fonts, as nginx defaults to the `application/octet-stream mimetype` for those filetypes. To fix this, add these lines to the `/etc/nginx/mime.types` config file:
|
||
|
|
|
||
|
|
```
|
||
|
|
font/ttf ttf;
|
||
|
|
font/opentype otf;
|
||
|
|
font/woff woff;
|
||
|
|
font/woff2 woff2;
|
||
|
|
```
|
||
|
|
|
||
|
|
Don't forget to add the first two to the list of gzipped mimetypes, the last two already have compression baked into the format:
|
||
|
|
|
||
|
|
```
|
||
|
|
gzip_types text/plain text/css ... font/ttf font/opentype;
|
||
|
|
```
|
||
|
|
|
||
|
|
In `/etc/nginx/nginx.conf` (on Debian).
