问题
I have created a web server socket using ws4py and which uses cherrypy. When I connect to the server using ip:port it connects perfectly and am able to chat through multiple browsers. However when I try to connect ip:port/ws it also works.
However, after I connect without using the ws, I am unable to handshake. I want to handle all request from client browser or it may another from different sources like using c# by this url ip:port/app and send payload from the client.
I have installed ws4py by this command sudo pip install ws4py and my server script is:

from ws4py.server.cherrypyserver import WebSocketPlugin, WebSocketTool

def received_message(self, m):
print "Message Received---------------------1"
print m
cherrypy.engine.publish('websocket-broadcast', m)
def closed(self, code, reason="A client left the room without a proper explanation."):
print "Socket Closed---------------------2"
cherrypy.engine.publish('websocket-broadcast', TextMessage(reason))
class Root(object):

Could you precsie what you mean by:
However, after I connect whithot using the ws, I am unable to handshake.
Do you mean you can't use the server at all afterwards? As a remainder, you can only perform websocket upgrade on the /ws path here since that's how you configured it at the bottom of your snippet.
