How To Enable Browser Cache in Nginx

What is a Browser Cache and What Does it Do?

A browser cache is a system of storing temporary internet files that are stored by your web browser when you visit websites on the internet. The main purpose of a browser cache is to make loading webpages faster by caching previously downloaded files. When you visit a website, the browser downloads some of the website’s data which is stored in the browser cache, and each time you visit the same website again, the data from the browser cache is used for faster loading. The browser cache also stores other elements such as images, javaScript, and CSS files. It is also used for things like auto-fill forms and passwords.

Benefits of Enabling Browser Cache in Nginx

Enabling browser caching helps to reduce the time it takes to download files from a web page by storing the files in the browser’s cache. This means that each time a visitor visits the same page, the file is already stored on their browser. This makes loading times much faster, since the browser does not have to download the file each time it is visited. As a result, it ensures that website visitors have a better experience, since they don’t have to wait long for page elements to load. Furthermore, it reduces strain on the server, because the files are already stored in the user’s browser, thereby reducing the amount of bandwidth needed.

Enabling Browser Cache on Nginx

Enabling browser caching on Nginx is fairly easy to do and can be done in two ways; either via the command line or via the Nginx configuration file. To enable browser cache via the command line, the following command line has to be run:

/usr/bin/nginx -t -c /etc/nginx/nginx.conf; sudo /etc/init.d/nginx reload

This command will enable the browser caching of files on Nginx. To enable browser caching via the Nginx configuration file, the following code has to be added to the configuration file:

location ~* .(jpg|jpeg|png|gif|ico|css|js|woff|ttf|svg)$ { expires 7d; add_header Cache-Control "public"; }

After the code is added to the configuration file, it must be saved and the server needs to be restarted for the changes to take effect. This will enable browser caching for the specified types of files.

Monitoring Cached Browser Data on Nginx

It is important to monitor cached browser data on Nginx, as it will help ensure that the data being cached is valid and up-to-date. To monitor the cached data, Nginx provides a tool called the Nginx Caching Tool which can be accessed via the command line or via the Nginx configuration file. This tool displays the current status of browser cache, the expiration date of cached files, and the response rate of the Nginx server. This tool is useful for keeping tabs on the caching performance of Nginx, and ensuring that the cached data is still valid and up-to-date.

Recommended Browser Cache Settings For Nginx

There are several recommended browser cache settings that should be used for Nginx in order to ensure that all files being cached are valid and up-to-date. Some of the recommended settings include setting a file expiration date of 7 days, ensuring that the ‘Cache-Control’ header is set to ‘public’, setting the ‘max-age’ to a value of 7 days, and setting the ‘Vary’ header to accept-encoding.

Troubleshooting Browser Cache Issues on Nginx

If there are any issues with the browser cache settings, there are several things that can be done to troubleshoot the issue. First, make sure that all the recommended settings are being used. Also, check to see if the Nginx Caching Tool is being used and if the cached data is valid and up-to-date. Lastly, it is important to ensure that the Nginx configuration file is correct and that it has been saved and restarted for the changes to take effect.

Conclusion

Browser caching is an important feature in Nginx as it helps to improve user experience by reducing page loading times, as well as reducing strain on the server. It is important to ensure that all the recommended settings are being used, and to keep track of cached data via the Nginx Caching Tool. By following these steps, it should be easy to enable browser caching and ensure that all browser cached data is valid and up-to-date.
