    <h1>Static File Server</h1>
    <p>cpp-httplibは、HTMLやCSS、画像ファイルなどの静的ファイルも配信できます。面倒な設定は要りません。<code>set_mount_point()</code> を1行呼ぶだけです。</p>
<h2>set_mount_point の基本</h2>
<p>さっそくやってみましょう。<code>set_mount_point()</code> は、URLのパスとローカルディレクトリを紐づけます。</p>

<p>第1引数がURLのマウントポイント、第2引数がローカルのディレクトリパスです。この例だと、<code>/</code> へのリクエストを <code>./html</code> ディレクトリから配信します。</p>
<p>試してみましょう。まず <code>html</code> ディレクトリを作って、<code>index.html</code> を置きます。</p>

<p>ハンドラーが先に評価されます。<code>/api/hello</code> にはハンドラーが応答し、それ以外のパスは <code>./public</code> ディレクトリからファイルを探します。</p>
<h2>レスポンスヘッダーの追加</h2>
<p><code>set_mount_point()</code> の第3引数にヘッダーを渡すと、静的ファイルのレスポンスにカスタムヘッダーを付けられます。キャッシュ制御に便利です。</p>

<p><code>./my-site</code> ディレクトリの中身が、そのままポート8080で配信されます。NGINXと同じログ形式で、アクセスの様子を確認できますよ。</p>
<h2>次のステップ</h2>
<p>静的ファイルの配信ができるようになりましたね。HTMLやCSS、JavaScriptを配信するWebサーバーが、これだけのコードで作れます。</p>
<p>次は、HTTPSで暗号化通信をしてみましょう。まずはTLSライブラリのセットアップからです。</p>
