public class HttpPutFormContentFilter
extends OncePerRequestFilter

Filter that makes form encoded data available through the ServletRequest.getParameter*() family of methods during HTTP PUT requests.

The Servlet spec requires form data to be available for HTTP POST but not for HTTP PUT requests. This filter intercepts HTTP PUT requests where content type is 'application/x-www-form-urlencoded', reads form encoded content from the body of the request, and wraps the ServletRequest in order to make the form data available as request parameters just like it is for HTTP POST requests.
