 - `port` (number) - When the `path` is provided as a local path on disk, the `port` on which to start the temporary web server.  Defaults to a random high range order port.
 - `recurse` (boolean) - By default, all scans are shallow.  Only the top level links on the requested page will be scanned.  By setting `recurse` to `true`, the crawler will follow all links on the page, and continue scanning links **on the same domain** for as long as it can go. Results are cached, so no worries about loops.
