 | ||
|  | ## 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). | ||
|  |
