I guess the method getInputStream is used for the developers who want to handle the request block themselves. Maybe the server could call some low-level methods in the implementation of the HttpServletRequest for request parsing. I suggest you could use the network monitor tool to log the request block. If you really want to do it in the server itself, maybe a third pary request parser is needed,such as commons-fileupload. I suppose the steps below could fulfill your requirements: 1. First using your current wrapper request to log the data 2. Pass your wrapper request to the commons-fileupload. maybe use new * ServletFileUpload**<http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/servlet/ServletFileUpload.html#ServletFileUpload%28%29> *() .parse(yourwrapperRequest) 3. For the method parse above returns a list object, you need to write another wrapper request, and overwrite some method in it (such as getParameter) to make your application works as usual
