| ## Gatsby.js Caching Static Sites
 | |
| 
 | |
| An important part of creating a very fast website is setting up proper HTTP caching. HTTP caching allows browsers to cache resources from a website so that when the user returns to a site, very few parts of the website have to be downloaded. Gatsby does this job automatically for you through Webpack.
 | |
| 
 | |
| HTML files should never be cached while all files in `public/static/` should be cached forever. Also, other files e.g. JavaScript files should also be cached forever.
 | |
| 
 | |
| ## Cache Controls Headers
 | |
| 
 | |
| HTML - The `cache-control` header should be `cache-control: public, max-age=0, must-revalidate`  
 | |
| Static Files (`/public/static`) - The `cache-control` header should be `cache-control: public,max-age=31536000,immutable`  
 | |
| JavaScript - The `cache-control` header should be `cache-control: public, max-age=31536000,immutable`  
 | |
| 
 | |
| ## Plugins
 | |
| 
 | |
| [Gatsby Plugin Netlify](https://www.gatsbyjs.org/packages/gatsby-plugin-netlify/) was created for automating caching when hosting your site at [Netlify](www.netlify.com).
