title: nginx custom error configuration referencing a string vs a file
body: <p>I understand that I can set a file for a custom error page:</p>
  
  <pre><code>location / {
      error_page 404 = /mybad.html;
  }
  </code></pre>
  
  <p>But I'd just like to instead provide my page override as text inline in the config file:</p>
  
  <pre><code> location / {
      error_page 404 = "&lt;H1&gt;Sorry!&lt;/H1&gt;"
  }
  </code></pre>
  
  <p>Is this possible with nginx?</p>
