Removing default octet mime type would be better... Just null would be nice.

And passing req.url with query parameters not working, only parsing url and passing parsed.pathname works. Would be nice to pass raw req.url and it gives proper mime.

here:
https://github.com/broofa/node-mime/blob/master/mime.js#L69

var results=path.match(/\.([a-z]+).*$/i);
if(results!==null && results[1]) {
var ext=results[1];
}
else {
return fallback || this.default_type;
}

return this.types[ext];

Regexp should be tested though.

Re: default type, see #139.
Re: urls, I'm not a big fan of overloading method arguments (allowing
String or Url), and would prefer not to add another method for this.
So, for now, I'm okay leaving this as a problem for the caller. mime.lookup(req.url.replace(/\?.*/,'')) works.
