How To Have Multiple Clients Listen To A Server Sent Event?

I am trying to get my head around server sent events. The rest of my site is served using cherrypy, so I want to get them working on this platform too. The method I'm using to expo

Solution 1:

Apparently I shouldn't be using a Queue. So I just needed to cut down my code to:

@cherrypy.expose
def interlocked(self, _=None):
    cherrypy.response.headers["Content-Type"] = "text/event-stream;charset=utf-8"
    if _:
        data = 'retry: 400\ndata: ' + str(self.isInterlocked) + '\n\n'
        return data
    else:
        def content():
            data = 'retry: 400\ndata: ' + str(self.isInterlocked) + '\n\n'
            return data
        return content()
interlocked._cp_config = {'response.stream': True, 'tools.encode.encoding':'utf-8'}
