A web cache is a tipically a software application for temporarily storing frequently-accessed static content.

Internet users with similar interests often download the same web content over and over again. Without a proper web cache, every time a user makes a request the response must come all the way from the origin server. When many users are requesting content at the same time, response times may increase and a server overload may even occur. A web cache handles requests for popular content that would otherwise be directed to the origin server. It also puts popular content closer to end users, thereby improving response times.

Whenever content is downloaded from the origin server, a copy is stored in the web cache for a set period of time determined by some caching rules. If another user requests the same content again, the web cache sends the stored content and the user request does not have to be forwarded to origin server again. This is known as content caching.

A typical web cache flow looks like this:

The increased use of websites and web applications demands higher bandwidth and server resources. However, organizations can still continue providing high Internet performance levels without increasing operational costs. This requires storing frequently-accessed web content and serving it locally. A hardware or software-based web cache placed between the users and web servers reduces bandwidth requirements, server load, and latency. This frees up resources while improving performance for users.
