Serving static files without directory browsing using Unfiltered and Jetty

How can I have unfiltered-jetty serve static files without allowing directory browsing?

Jetty has the dirAllowed setting, but it does not seem easily accessible from Unfiltered.

Solution

  • This is working with Unfiltered 0.8.4 which uses Jetty 8:

    import org.eclipse.jetty.server.handler.{HandlerCollection,ContextHandler}
import org.eclipse.jetty.server.Handler

  def disableDirBrowsing(hc: Array[Handler]) {
    hc.map { h =>
      h match {
        case nested: HandlerCollection => disableDirBrowsing(nested.getHandlers)
        case c: ContextHandler =>
          c.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false")
        case _ => // ignore everything else
      }
    }
  }

    If srv is your Unfiltered server object after adding contexts to it, you can now disable directory browsing like so:

    disableDirBrowsing(srv.underlying.getHandlers)
