[Twisted-web] Deferred in proxy.ProxyClient.handleHeader

[Ing. Stefan Grosz, BSc]

hi!

i'm currently writing a reverse proxy with twisted and i've a problem with a
deferred
function in my handleHeader method.

the code looks simplified like this:

class MyProxyClient(proxy.ProxyClient):
@defer.inlineCallbacks
def handleHeader(self, key, value):
if key.lower() == 'location':
clientCreator = protocol.ClientCreator(reactor, Redis, db=3)
redis = yield clientCreator.connectTCP("localhost", 6379)
value = yield redis.get('myproxy:hashcode:%s' % value)
proxy.ProxyClient.handleHeader(self,key,value)


as the handleHeader caller doesn't wait for a deferred to finish, the
location header is
added after handleResponseEnd is already called and therefore never makes it
to the client.

is there a way to convert the non-blocking redis call to a blocking redis
call?
i know that there's a blocking client library for redis but i'd rather use
only txredis if possible.


regards,
  stefan
