public class SizeLimitHandler extends Handler.Wrapper
A handler that can limit the size of message bodies in requests and responses.

The optional request and response limits are imposed by checking the Content-Length header or observing the actual bytes seen by the handler. Handler order is important, in as much as if this handler is before a the GzipHandler, then it will limit compressed sized, if it as after the GzipHandler then the limit is applied to uncompressed bytes. If a size limit is exceeded then BadMessageException is thrown with a HttpStatus.PAYLOAD_TOO_LARGE_413 status.

    • handle

      public boolean handle(Request request, Response response, org.eclipse.jetty.util.Callback callback) throws Exception
      Description copied from interface: Request.Handler

      Invoked to handle the passed HTTP request and response.

      The request is accepted by returning true, then handling must be concluded by completing the passed callback. The handling may be asynchronous, i.e. this method may return true and complete the given callback later, possibly from a different thread. If this method returns false, then the callback must not be invoked and any mutation on the response reversed.

      Exceptions thrown by this method may be subsequently handled by an error Request.Handler, if present, otherwise a default HTTP 500 error is generated and the callback completed while writing the error response.

      The simplest implementation is:

       public boolean handle(Request request, Response response, Callback callback)
 {
     callback.succeeded();
     return true;
 }

      A HelloWorld implementation is:

       public boolean handle(Request request, Response response, Callback callback)
 {
     response.write(true, ByteBuffer.wrap("Hello World\n".getBytes(StandardCharsets.UTF_8)), callback);
     return true;
 }
      Specified by:
      handle in interface Request.Handler
      Overrides:
      handle in class Handler.Wrapper
      Parameters:
      request - the HTTP request to handle
      response - the HTTP response to handle
      callback - the callback to complete when the handling is complete
      Returns:
      True if and only if the request will be handled, a response generated and the callback eventually called. This may occur within the scope of the call to this method, or asynchronously some time later. If false is returned, then this method must not generate a response, nor complete the callback.
      Throws:
      Exception - if there is a failure during the handling. Catchers cannot assume that the callback will be called and thus should attempt to complete the request as if a false had been returned.
