Description of problem:

Any file or asset in the public folder in a rails app is sometimes incorrectly passed to Rails rather than being handled by the web server resulting in a HTTP 404 and a "ActionController::RoutingError (No route matches [GET] "/assets/planner-d21570b2b5627da0866a521833ce84ab.css")" error in the appropriate rails log.

Requests for files in the public directory follow a repeatable pattern: 200 - 404 - 200 - 404 ... (every other request fails by being passed to rails resulting in a 404)
