In today's competitive world with ever decreasing attention span of users faster loading and uptime could turn out to be a make or break factor for your business.

More and more users are using mobile devices every day making lighter and faster pages a necessity.

Businesses with a worldwide audience need their website uptime to be 100%. Each minute downtime would mean an opportunity loss and bad user experience.

Tools like nginx, page speed insights by google and uptime robot can be easily used to not only improve the user experience but also monitored constantly for downtimes.

10X Faster Page Load With Caching

Caching can be a quick solution to the speed up the page load time. You can cache dynamic resources on your website and provide faster reply times along with reducing the load on application logic.

Also caching static resources ensures the fastest retrieval for stored data from the website.

Nginx is a high-performance web server which facilitates caching of your website resources.

Setup Caching In Nginx

Setting up Nginx caching can be done easily by using the two commands in the default configuration of Nginx at /etc/nginx/sites-available/default

  • proxy_cache_path : details about the cache store.
  • proxy_cache : mapping the paths to the cache store.

Handling Service Downtime With Cached Resources

Nginx can also serve stale content when the original service is down using the directive:

  • proxy_cache_use_stale : enables serving the stale cache for certain HTTP reply from original service.

Optimizing Cache To Improve Performance

You can customize how to cache resources using the following directives:

  • proxy_cache_revalidate : validates if fresh content is available.
  • proxy_cache_min_uses : number of times a item must be requested before caching it.
  • proxy_cache_background_update : stale resources are updated in background
  • proxy_cache_lock : ensures a single original resource request is made in a multiple client requests scenario instead of multiple requests.
  • split_clients : store cache across hard drives.
  • proxy_cache_methods : cache resources based on HTTP request type.
  • proxy_cache_bypass : for bypassing cached resources.
