    <h1>Static File Server</h1>
    <p>cpp-httplib can serve static files too — HTML, CSS, images, you name it. No complicated configuration required. One call to <code>set_mount_point()</code> is all it takes.</p>
<h2>The basics of set_mount_point</h2>
<p>Let's jump right in. <code>set_mount_point()</code> maps a URL path to a local directory.</p>

<p>The first argument is the URL mount point. The second is the local directory path. In this example, requests to <code>/</code> are served from the <code>./html</code> directory.</p>
<p>Let's try it out. First, create an <code>html</code> directory and add an <code>index.html</code> file.</p>

<h2>Combining with handlers</h2>
<p>Static file serving and routing handlers — the kind you learned about in the previous chapter — work side by side.</p>

<p>Handlers take priority. The handler responds to <code>/api/hello</code>. For every other path, the server looks for a file in <code>./public</code>.</p>
<h2>Adding response headers</h2>
<p>Pass headers as the third argument to <code>set_mount_point()</code> and they get attached to every static file response. This is great for cache control.</p>

<h2>A Dockerfile for your static file server</h2>

<p>Everything in your <code>./my-site</code> directory gets served on port 8080. The access log follows the same format as NGINX, so you can see exactly what's happening.</p>
<h2>What's next</h2>
<p>You can now serve static files. A web server that delivers HTML, CSS, and JavaScript — built with this little code.</p>
<p>Next, let's encrypt your connections with HTTPS. We'll start by setting up a TLS library.</p>
