NoOpServlet is a dummy servlet used only to provide a servlet mapping for url patterns that dont have any. This is
necessary as some application servers like WebSphere 6.1.0.5 returns a 404 if there are no mapped servlet before
applying filters to the request which could potentially change the URL mapped to a valid servlet. For example, the
URLRewriter filter does this. Hence this dummy servlet should never handle any requests.
If this servlet receives a request, it will simply log all relevant information from the request that may be of help
in determining why the request was received, as this would not be the desired result.
