title: How do I make every file in a static dir have Content-Type ... using express?
body: <p>I have a dir that contains anywhere between zero and a few hundre files, all without extension (generated in an unknowable nested dir structure by another app, with the writing occurring somewhere in a library that I can't, nor want, to modify code in), with all files containing html content. I'd like to use express's convenient <code>static</code> call so I don't have to worry about which files exist, but</p>
  
  <pre><code>app.use(express.static("..."))
  </code></pre>
  
  <p>does not let me say that all the content from this dir should be <code>Content-Type text/html</code>. Is there a way to to serve up content from anywhere in that dir (without knowing what's in it) with the response header always saying the content is text/html?</p>
