### Use Google Hosted JS (Canonicalize Javascript Libraries)

This is handy when you want to allow some of the more common javascript files to load from Google's servers.
See here: https://developers.google.com/speed/pagespeed/module/filter-canonicalize-js

```bash
bash scripts/pagespeed_libraries_generator.sh > ~/pagespeed_libraries.conf
sudo cp ~/pagespeed_libraries.conf /etc/nginx/
```

In the Nginx.conf file above, right after you say pagespeed on; add this

Sorry, I just meant that I wanted "pagespeed on" to be surrounded in backticks so it would show up monospaced and look like a command. But I did this when I merged it, so no worries.


```nginx
include pagespeed_libraries.conf;
pagespeed EnableFilters canonicalize_javascript_libraries;
```

Now most of your common JS files will load from //ajax.googleapis.com/...
