Q1Domain Verified

Within the context of building a robust web server in Go using the `net/http` package, what is the primary advantage of using `http.ServeMux` over a custom-built routing mechanism for simple applications?

`http.ServeMux` is designed for high-concurrency scenarios and outperforms custom solutions in terms of raw request throughput.

`http.ServeMux` offers advanced middleware support out-of-the-box.

`http.ServeMux` provides a built-in, efficient, and standard way to multiplex incoming HTTP requests to specific handlers based on URL patterns.

`http.ServeMux` automatically handles request body parsing for all content types.

Q2Domain Verified

When implementing a custom `http.Handler` in Go, what is the critical responsibility of the `ServeHTTP` method regarding response writing and signaling completion?

The `ServeHTTP` method must return an `error` to indicate if the response was successfully sent.

The `ServeHTTP` method must explicitly close the `http.ResponseWriter` to signal the end of the response.

The `ServeHTTP` method is responsible for writing the entire response (headers and body) and ensuring the connection is implicitly managed by the underlying HTTP server.

The `ServeHTTP` method should only write headers and defer writing the body until a subsequent request is received.

Q3Domain Verified

Consider a scenario where you need to serve static files from a directory. What is the most idiomatic and secure approach using the `net/http` package in Go to achieve this, preventing directory traversal vulnerabilities?

Implement a custom handler that manually reads files and serves them, sanitizing all file paths.

Use `http.FileServer` in conjunction with `http.StripPrefix` to serve files from a specific sub-directory, ensuring the prefix is correctly handle

Use `http.FileServer(http.Dir("."))` directly to serve files from the current directory.

D) Employ `http.ServeContent` for each file individually, dynamically generating the `http.Dir` object for each request.
