How does file caching affect the web application?

When content is cached, subsequent requests for the same resource are served directly from the cache without reaching the web application server. This means the application does not need to execute logic, query databases, or generate dynamic responses for cached requests, directly reducing its computational load.

Caching does not inherently speed up traffic to the application - it reduces requests that reach it, but traffic speed is governed by network bandwidth and latency, not caching.

Caching reduces, not slows, traffic to the web application by intercepting repeated requests before they reach the server.

Caching offloads repeated requests away from the server, which reduces rather than increases the load on the web application.
