Hello,

I'm just getting started with twisted and have a question about twisted web. How would I go about limiting the web server to accepting a single connection? I know you might be asking your self why anyone would want to do such a stupid thing, but I'm controlling some hardware and need to restrict access to it to a single user at a time.

Anyway, I'd appreciate any pointers. :-)

You'll probably have to subclass twisted.web.server.Site to make buildProtocol return None if a connection is active. Untested code from the top of my head: from twisted.protocols.http import HTTPChannel from twisted.web.server import Site class SingleConnectionHTTPChannel(HTTPChannel): def connectionLost(self, reason): self.factory.connections -= 1 HTTPChannel.connectionLost(self, reason) class SingleConnectionSite(Site): protocol = SingleConnectionHTTPChannel connections = 0 def buildProtocol(self, addr): # Reject concurrent connections if self.connections: return None self.connections += 1 return Site.buildProtocol(self, addr) -Andrew.
