hi, i resolved the problem.

use twisted.web2.stream.ProducerStream when getPage function is finished, then write data to the stream.

class Test(resource.Resource): def render(self, request): remoteurl = 'http://www.sf.org/' from twisted.web2.stream import ProducerStream responseStream = ProducerStream() getPage(remoteurl, timeout=60).addCallback(self.reqok, request, responseStream).addErrback(self.reqfailure, request, responseStream) return http.Response(200, {'content-type': contenttype} ,responseStream)

def reqok(self, result, request, responseStream): responseStream.write(result) responseStream.finish()

def reqfailure(self, failure, request, responseStream): responseStream.write('Bad Request') responseStream.finish()<twisted-web%40twistedmatrix.com?Subject=%5BTwisted-web%5D%20web2%20and%20database%20handling&In-Reply-To=45802378.6000605%40ag-projects.com>
