This is how you want to do it, there should be no surprises with this 
approach (it handles failures, logs to stdout):

from twisted.web import server, resource, static, script
from twisted.internet import reactor, threads
from twisted.python import log
import sys

def doLongPageGeneration(request):
     # you *could* inspect the request object if you needed to from here
     # but I wouldn't *change* it from this thread!
     return "<html><b>H</b>ello, <b>W</b>orld! - Your user agent is 
%s</html>" % request.getHeader('user-agent')

def writeRequestAndFinish(data, request):

class Simple(resource.Resource):
     isLeaf = True
     def render(self, request):
         return server.NOT_DONE_YET

site = server.Site(Simple())
reactor.listenTCP(8080, site)
# I'm not sure if this is strictly necessary, but it seems like a good
