You're tasked with implementing an HTTP server that serves both static files and dynamic content. How would you structure your Go program to handle this requirement efficiently?

Using a router like Gorilla Mux allows for efficient routing of requests to either static file paths or dynamic routes, optimizing server performance by reducing unnecessary processing for each request. Gorilla Mux provides powerful routing capabilities and can efficiently handle complex routing requirements. This approach ensures clean code separation and scalability, making maintenance and updates easier in the future. Middleware can also be employed but might lead to increased complexity and potential performance overhead compared to a dedicated router solution. Combining net/http's ServeFile for static files and custom handlers for dynamic content could work, but it lacks the robustness and flexibility provided by a dedicated router. Utilizing HTTP request headers for differentiation might introduce unnecessary complexity and potential maintenance issues, making it less desirable compared to using established routing solutions.
