Learning the Distinction between Server and Browser Caches

The experience of using the internet is not complete without the cache. However, there are many questions regarding this internet function.  

Should you frequently clear your cache? Will your settings be altered? Do you anticipate losing system data? What distinguishes server cache from browser cache?

The majority of these queries are brought on by users’ ignorance of one of the fundamental elements of the networked world. 

This essay dispels any misconceptions, clarifies the issues, and provides you with a comprehensive grasp of what a cache is and how it differs between a server cache and a browser cache.

Continue reading to learn what experienced web developers have to say.

Describing a Cache

A cache can be thought of as a place to keep temporary files that are utilised to speed up page loads, enhance user experience, and improve the device, app, or browser performance. 

For later visits, preloading material, such as multimedia data, decreases the load time and shortens downtime. The cache is frequently updated to reflect new content.

Caching serves as a kind of shortcut to conserve resources and speed up web browsing. Images, videos, unique typefaces, and other components may be found on a web page. These are the types of information that are typically kept in a cache.

Depending on where the memory is kept, there are three types of caches: site cache, server cache, and browser cache.

Understanding the Server Cache

A cache that is kept on the server side of a connection is called a server cache. The best way to lessen server loads is to use this cache. When a request comes in, the server first checks its cache before serving any previously downloaded files. 

This significantly shortens the loading process. This helps high-traffic websites return web pages more quickly.

Many different types of caches can be grouped under the server cache. The most typical ones are the following:

  • Object Cache: Database queries employ this type of cache for quick retrieval and quicker page loading.
  • CDN Cache: The content delivery network (CDN) cache is a collection of servers dispersed across the globe. To speed up page loading, the server that is nearest to the user will return cached material.
  • Opcode Cache: This cache saves precompiled code, saving PHP from loading and parsing scripts for each request.

Understanding the Browser Cache

The user’s browser contains a cache, as the name suggests. The user’s hard drive houses the browser cache. Thanks to a browser cache, every component of a webpage does not have to be downloaded for each subsequent visit. 

For instance, a page you frequently visit will include a lot of components like icons and logos that remain constant over time. In order to speed up download on subsequent trips, saving these photographs from the initial visit is useful.

Clearing the Cache

The majority of web developers advise often deleting cache, which is the user’s browser cache. Because caches are memory stores, they occupy space. It makes sense to periodically clear the cache because the data stored therein is prone to being out-of-date.


Site formatting and loading problems can be fixed by clearing the cache. Your saved account and password will be removed, which is a drawback. The following time, you must enter them again and save them. 

Your system files are not deleted when you clear the cache, though. Only temporary files saved by your browser are deleted throughout the procedure.
