+# Website
+
+This website is built using [Docusaurus](https://docusaurus.io/), a modern static website generator.
+
+### Installation
+
+```
+$ yarn
+```
+
+### Local Development
+
+```
+$ yarn start
+```
+
+This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
+
+### Build
+
+```
+$ yarn build
+```
+
+This command generates static content into the `build` directory and can be served using any static contents hosting service.
+
+### Deployment
+
+Using SSH:
+
+```
+$ USE_SSH=true yarn deploy
+```
+
+Not using SSH:
+
+```
+$ GIT_USER=<Your GitHub username> yarn deploy
+```
+
+If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.

+/// 1. Extracts the `Host` header from the incoming request.
+/// 2. Parses the host string to determine the port (defaulting to `80` if unspecified).
+/// 3. Looks up the host configuration in the global `HOST` map (shared state) for the resolved port.

+///
+/// # Behavior
+/// - If the `Host` header is missing or malformed, the request proceeds unchanged.
+/// - If the port is invalid or the host configuration is not found, the request proceeds unchanged.
+/// - Headers are appended to the response only if they are explicitly configured for the host.
+///
+/// # Error Handling
+/// - Silently skips header addition for:
+///   - Missing or unparseable `Host` headers.
+///   - Invalid ports (non-numeric or out-of-range).
+///   - Missing host configurations in `HOST`.
+/// - Uses `debug!` for logging the resolved port.

+/// Given a request to `example.com:8080` and a `HOST` entry for port `8080` with headers:

+// Asynchronously waits for a shutdown signal and executes a callback function when a signal is received.
+//
+// This function listens for shutdown signals in the form of `Ctrl+C` and termination signals. When one of
+// these signals is received, it invokes the provided callback function `shutdown_cb`.
+//
+// The behavior of the signal handling depends on the operating system:
+//
+// - On Unix-based systems (e.g., Linux, macOS), it listens for termination signals (such as SIGTERM).
+// - On non-Unix systems (e.g., Windows), it only listens for `Ctrl+C` and ignores termination signals.
+//
+// The `shutdown_cb` callback function is executed when either signal is received. This function should
+// contain the logic needed to gracefully shut down the application or perform any necessary cleanup tasks.
+// # Parameters
+//
+// - `shutdown_cb`: A closure or function to call when a shutdown signal is received. The function should
+//   have the signature `Fn()`. This callback is executed without any parameters.
+//
+// # Errors
+//
+// - If setting up the signal handlers fails, the function will panic with an error message.
+//
+// # Panics
+//
+// - Panics if the setup for `Ctrl+C` or termination signal handlers fails.
+//
+// # Platform-specific behavior
+//
+// - On Unix-based systems, termination signals are handled using the `signal` crate for Unix signals.
+// - On non-Unix systems, only `Ctrl+C` signals are handled, and termination signals are not supported.
+//

+// and the callback function has been executed.
