Browser sends http request with RANGE

I have a local testing environment in a Fedora virtual machine. Strangely, resources (css and js files) don't seem to work. Looking at Firebug, I see that the browser sends the HTTP request with "Range bytes=0-". The server responds with either an empty 200OK or an empty 206 Partial Content.

Here is an example:

I don't know if the browser is sending the wrong request, or if it's the server that is doing this. Request made to the outside (such as google analytics) are working fine.

This is running in Fedora 11 in VirtualBox. Apache. PHP. The files are being served through the "shared folders" feature of VirtualBox (could it be related?).

No error logs could help me.

• Is there a chance that the account used to run apache / php doesn't have access to read the files from the "shared folders"? From your description it sounds like PHP doesn't have the problem, just the static files (so apache then?) ... maybe try creating a PHP wrapper to stream them?

  if ($fp = fopen ($file_path, "r")) {
      while(!feof($fp)) {
          $file_buffer = fread($fp, 2048);
          echo $file_buffer;
      }
      fclose($fp);
  } else {
      die('LOGGED! bad file '.$file_path);
  }

• This indicates that your server accepts the Range: header from the client, using the Byte format. Range is used for "Progressive download", also called "Resuming a download". When you download a file in Firefox for instance, using HTTP (not FTP), hit "Pause" and then "Resume", Firefox will send an HTTP GET to the server and add a Range: header in the request. The value of that header will indicate to the server what byte offset to start the data stream at.

  This header is optional, according to the HTTP 1.1 Header Fields Definition RFC. That means the clients will still try to send the Range: header, but the server will just ignore it if it doesn't support that kind of requests. Therefore I would disable it because it just adds unnecessary bandwidth usage to your server.
