I test the WS continuation feature, anyway we cannot use it, for the
* When browser receives unfinished frame it doesn't raise the onmessage
event and wait for the last frame, then concatenating all the frames. You
don't have a way to know where the frame begin and end, for example two
frames messages, first is "Hello" and second is "World" the message will
just be "HelloWorld"
