Website caching reduces requests to your origin server by reusing a stored response when a later request matches and the response is still safe to serve. A browser cache can spare repeat downloads for one visitor; a shared cache, such as a CDN, can serve reusable content to many visitors. The title’s “thousands” is illustrative, not a measured result or guarantee.
How caching reduces work at your origin
An HTTP cache stores a response associated with a request and may reuse it for later matching requests. When a request arrives, a cache checks whether it has a reusable response. If so, it returns that copy instead of fetching the resource from the origin (your website’s server). If not, it forwards the request to the origin and may store the response for later, provided the response and cache policy allow it. MDN’s HTTP caching guide describes this response-reuse model.
A cache hit can avoid both a trip to the origin and repeated origin-side work: handling and routing the request, restoring a session, querying a database, or rendering a page. A cache miss still reaches the origin. Some shared caches can also collapse simultaneous identical requests: they make one origin request and share its result with clients waiting for the same resource. That can help during a burst, but the number of requests saved depends on the traffic, cache rules, and how much requested content is reusable.

Browser cache or shared cache?
The cache’s location determines who can benefit from a saved response. A browser cache is private to an individual client, while a shared cache—such as a proxy or CDN—can serve multiple users when the response is suitable for sharing.

| Cache type | Who can reuse the response | Typical effect |
|---|---|---|
| Browser (private) cache | The same visitor’s browser | A repeat visit can avoid downloading a still-fresh resource again. |
| Shared cache | Multiple visitors, when the response and policy permit sharing | Matching requests can be served without each reaching the origin. |
A browser cache primarily benefits repeat visits by the same person. A shared cache can help when different visitors request the same cacheable content, such as a public image or other reusable asset.
How freshness and Cache-Control work
The HTTP Cache-Control response header tells browsers and shared caches whether a response can be stored, how long it can be considered fresh, and whether it must be checked with the origin before reuse. Common directives include:

- 【One data Center Across Your Devices】Keep files from desktops, laptops, phones, tablets, and other devices together instead of scattered across cloud accounts and external drives. Access, back up, organize, and share data across Windows, macOS, Android, iOS, web browsers, and compatible smart TVs—ideal for creators and advanced home users working across multiple devices.
max-age=N: the response is fresh for the specified number of seconds after generation, subject to its age and other applicable rules.no-cache: a stored response must be successfully validated before reuse. It does not mean “do not store.”no-store: instructs caches not to store the request or response.private: reserves the response for a private cache rather than a shared cache.public: indicates that shared caches may store a response in applicable situations; it does not make personalized content safe to share.
Freshness and validation are different. A fresh cache hit can be served without contacting the origin. Once a response is stale, a cache may ask the origin to validate it. If it is still valid, the cache can reuse its stored body, but validation still involves the origin. See MDN’s Cache-Control reference for directive details.

A CDN places shared caches in distributed data centers so content can be served nearer to visitors. When a visitor’s request matches a reusable response at an appropriate cache, the CDN can answer without fetching that content from the origin. If the cache does not have a usable copy, it must fetch from the origin; a CDN does not eliminate origin traffic for every request.

Behavior depends on the provider and configuration. For example, Cloudflare’s documentation says that, with Origin Cache Control enabled, a max-age of 3,600 seconds means it caches a resource for that period before checking the origin again. Cloudflare also says its Cache Rules can augment or override origin directives or default policies. Those details apply to Cloudflare’s documented behavior, not all CDNs. See Cloudflare’s Origin Cache Control documentation and Cloudflare’s cache setup guide.
When evaluating or configuring a shared cache, check:

- SDI Rates: 1.5G, 3G, 6G, 12G
- HDMI Video Outputs: 1 x monitor out
- Webcam Output: 1 x Type USB-C
- Which assets or pages are eligible to be cached.
- Whether the response is private to one user or shareable.
- How long a response stays fresh and what happens when it becomes stale.
- How you invalidate or purge old copies after content changes.
- Whether the provider follows your origin’s headers or applies rules that override them.
- What happens on a cache miss, and whether the origin can handle that traffic.
Keep personalized responses out of unsafe shared caches
A shared cache can expose one user’s response to another if its cache key or rules do not account for personalization. Account pages, checkout flows, and other user-specific responses therefore need careful handling. MDN recommends private when a response is personalized and should not be shared; web.dev’s HTTP cache security guidance explains how misconfiguration can create security and privacy problems. Use private-cache behavior where appropriate, and do not assume that marking a response public makes sensitive content safe to cache.
What “thousands of requests” really means
Caching can prevent repeated origin requests, but there is no universal reduction figure established here. The result depends on how many requests match cached responses, how long those responses remain fresh, whether users request personalized content, and how the cache handles misses and validation. The practical takeaway is the mechanism: reusable responses can reduce repeated origin work, while misses, stale-response checks, and uncached or user-specific requests still require origin involvement.
