// In Program.cs
app.MagGet("/", (HttpContext context) =>
	{
    	string userAgent = "";

  		// Get request header values like Content-Type, User-Agent, etc.
        if (context.Request.Headers.ContainsKey("User-Agent"))
        {
        	userAgent = context.Request.Headers["User-Agent"];
        }

  		// Set response header values like Content-Type, etc.
  		context.Response.Headers["Content-Type"] = "text/html"; // default is "text/plain"

		return $"<h2>User Agent: {userAgent}</h2>";
    }
);

app.Run(async (HttpContext context) =>
{
    if (context.Request.Path == "/Hello")
    {
        context.Response.StatusCode = 200;
	    await context.Response.WriteAsync("Hello world!");
    }
    else if (context.Request.Path == "/Nowhere")
    {
        context.Response.StatusCode = 404;
	    await context.Response.WriteAsync("Page not found!");
    }
});
