Nginx Cache: Breakdown
...
The Nginx Cache plugin predominantly functions to enhance the speed and overall performance of WordPress websites. It does so by leveraging the Nginx's caching capabilities efficiently. For a website to function, several processes happen in the background. Each time a visitor accesses a webpage, a request is made to the server to fetch the relevant content, then the page is rendered for the user to view. The more complex the website - with various plugins, themes, and databases - the longer it takes for the content to load.
Recognizing that these delays could affect user experience and SEO rankings, the creators of the 'Nginx Cache' plugin developed a way to improve this situation. It works by storing a copy of the website's files in a cache for quicker retrieval. Meaning, instead of fetching a page's content from the server each time it's accessed, the plugin retrieves a static version of the page stored in the cache, significantly reducing loading times.
Furthermore, Nginx Cache enables manual and automatic purging of the cache. When content is updated, the corresponding cache must also be refreshed to deliver the most recent version of the content to website visitors. This plugin ensures a smooth transition between cache updates so that visitors always get the latest content with the benefit of the cache speed improvement.
Another important feature is its compatibility. Unlike other caching plugins, Nginx Cache was specifically designed to work effectively with the Nginx server structure, providing remarkable performance improvement. Moreover, it is compatible with most WordPress themes and plugins, making it a highly versatile solution for website administrators seeking to improve their website's speed and performance.
