The Data Localization Suite (DLS) is a collection of tools that enable customers to choose the location where Cloudflare inspects and stores data, while maintaining the security and performance benefits of our global network.| Cloudflare Docs
With DNS over HTTPS (DoH), DNS queries and responses are encrypted and sent via the HTTP, HTTP/2 and HTTP/3 protocols. DoH ensures that attackers cannot forge or alter DNS traffic. DoH uses port 443, which is the standard HTTPS traffic port, to wrap the DNS query in an HTTPS request. DNS queries and responses are camouflaged within other HTTPS traffic, since it all comes and goes from the same port.| Cloudflare Docs
1.1.1.1 is Cloudflare’s public DNS resolver. It offers a fast and private way to browse the Internet. DNS resolvers translate domains like cloudflare.com into the IP addresses necessary to reach the website (like 104.16.123.96).| Cloudflare Docs
If you want to use Cloudflare as your primary DNS provider and manage your DNS records, your domain should be using a full setup.| Cloudflare Docs

With Cloudflare Zero Trust, you can create a private network between any two or more devices running Cloudflare WARP. This means that you can have a private network between your phone and laptop without ever needing to be connected to the same physical network. If you already have an existing Zero Trust deployment, you can also enable this feature to add device-to-device connectivity to your private network with the press of a button. This will allow you to connect to any service that relies ...| Cloudflare Docs
Locally-managed tunnels run as an instance of cloudflared on your machine. You can configure cloudflared properties by modifying command line parameters or by editing the tunnel configuration file.| Cloudflare Docs
Cloudflare Tunnel provides you with a secure way to connect your resources to Cloudflare without a publicly routable IP address. With Tunnel, you do not send traffic to an external IP — instead, a lightweight daemon in your infrastructure (cloudflared) creates outbound-only connections to Cloudflare's global network. Cloudflare Tunnel can connect HTTP web servers, SSH servers, remote desktops, and other protocols safely to Cloudflare. This way, your origins can serve traffic through Cloudfl...| Cloudflare Docs
The Cloudflare WARP client allows you to protect corporate devices by securely and privately sending traffic from those devices to Cloudflare's global network, where Cloudflare Gateway can apply advanced web filtering. The WARP client also makes it possible to apply advanced Zero Trust policies that check for a device's health before it connects to corporate applications.| Cloudflare Docs

Workflows allow you to build durable, multi-step applications using the Workers platform. A Workflow can automatically retry, persist state, run for hours or days, and coordinate between third-party APIs.| Cloudflare Docs
A Workflow contains one or more steps. Each step is a self-contained, individually retriable component of a Workflow. Steps may emit (optional) state that allows a Workflow to persist and continue from that step, even if a Workflow fails due to a network or infrastructure issue.| Cloudflare Docs
Use AI Gateway for analytics, caching, and security on requests to Workers AI. Workers AI integrates seamlessly with AI Gateway, allowing you to execute AI inference via API requests or through an environment binding for Workers scripts. The binding simplifies the process by routing requests through your AI Gateway with minimal setup.| Cloudflare Docs
An Agent can schedule tasks to be run in the future by calling this.schedule(when, callback, data), where when can be a delay, a Date, or a cron string; callback the function name to call, and data is an object of data to pass to the function.| Cloudflare Docs

ECH stands for Encrypted Client Hello. It is a protocol extension in the context of Transport Layer Security (TLS). ECH encrypts part of the handshake and masks the Server Name Indication (SNI) that is used to negotiate a TLS session. This means that whenever a user visits a website on Cloudflare that has ECH enabled, intermediaries will be able to see that you are visiting a website on Cloudflare, but they will not be able to determine which one.| Cloudflare Docs
Cloudflare's Instant Purge ensures that updates to your content are reflected immediately. Multiple options are available for purging content, with single-file cache purging (purge by URL) being the recommended method. However, the following additional options are also available:| Cloudflare Docs
Cache Reserve is a large, persistent data store implemented on top of R2. By pushing a single button in the dashboard, your website’s cacheable content will be written to Cache Reserve. In the same way that Tiered Cache builds a hierarchy of caches between your visitors and your origin, Cache Reserve serves as the ultimate upper-tier cache that will reserve storage space for your assets for as long as you want. This ensures that your content is served from cache longer, shielding your origi...| Cloudflare Docs

Edge Cache TTL (Time to Live) specifies the maximum time to cache a resource in the Cloudflare global network. Edge Cache TTL is not visible in response headers and the minimum Edge Cache TTL depends on plan type.| Cloudflare Docs
Cloudflare’s Always Online feature is now integrated with the Internet Archive so that visitors can access a portion of your website even when your origin server is unreachable and a Cloudflare-cached version is unavailable. When your origin is unreachable, Always Online checks Cloudflare’s cache for a stale or expired version of your website. If a version does not exist, Cloudflare goes to the Internet Archive to fetch and serve static portions of your website.| Cloudflare Docs
Vary is an HTTP response header that allows origins to serve variants of the same content that can be used depending on the browser sending the request.| Cloudflare Docs

While your DNS records make your website or application available to visitors and other web services, the Proxy status of a DNS record defines how Cloudflare treats incoming DNS queries for that record.| Cloudflare Docs
To optimize your website or web application, Cloudflare provides DNS and CDN services, so we can reverse proxy the web traffic to and from your domain.| Cloudflare Docs
This page describes expected limitations when proxying DNS records. For further information about proxying, refer to How Cloudflare works.| Cloudflare Docs
Public Bucket is a feature that allows users to expose the contents of their R2 buckets directly to the Internet. By default, buckets are never publicly accessible and will always require explicit user permission to enable.| Cloudflare Docs
Tiered Cache uses the size of Cloudflare’s network to reduce requests to customer origins by dramatically increasing cache hit ratios. With data centers around the world, Cloudflare caches content very close to end users. However, if a piece of content is not in cache, the Cloudflare edge data centers must contact the origin server to receive the cacheable content.| Cloudflare Docs
Cache stores copies of frequently accessed content (such as images, videos, or webpages) in geographically distributed data centers that are located closer to end users than origin servers, reducing server load and improving website performance.| Cloudflare Docs

To use redirects on Cloudflare Pages, declare your redirects in a plain text file called _redirects without a file extension, in the output folder of your project. The build output folder is project-specific, so the _redirects file should not always be in the root directory of the repository. Changes to redirects will be updated to your website at build time so make sure you commit and push the file to trigger a new build each time you update redirects.| Cloudflare Docs
