Log the value of req.connection.id in the request to try and doubly confirm if it is being done in context of one client connection. Do you have any fancy rewrite rules in your Apache configuration? Do you have directory browsing enabled in Apache so you can get directory listings? Are you using any Apache authentication scheme?
