[Twisted-web] reverse proxy with nevow

[Mike Mueller]

After fiddling for quite a while I am running out of ideas how get the 
following to work.

I would like to run a nevow site on port 8080 on the same machine I run a 
twisted web
server that serves static pages. Instead of showing the 8080 in the address 
I would like
to run the nevow site as VHostMonsterResource.

My twisted web server looks like this:

#twistedStaticServer.py

from twisted.web import vhost, static, server, proxy
from twisted.application import internet, service
import os

vhostDir = '..\hosts'
root = vhost.NameVirtualHost()
dir = 'domain1.com'
root.addHost(dir, static.File(os.path.join(vhostDir, dir)))
vhostName = 'domain2.com'
reverseProxy = proxy.ReverseProxyResource('localhost', 8080,
                                           '/vhost/http/'+vhostName)
root.addHost(vhostName, reverseProxy)
application = service.Application('web')
sc = service.IServiceCollection(application)
site = server.Site(root)
i = internet.TCPServer(80, site)
i.setServiceParent(sc)

The nevow site looks like this:

#nevowProxy.py

import random
from nevow import appserver, vhost
from twisted.application import internet, service
from nevow import rend, tags
from nevow import loaders

vResource = vhost.VHostMonsterResource()

class VHostGreeter(rend.Page):
     docFactory = loaders.stan(
     tags.html[
     tags.head[ tags.title[ "Runnig as VHostMonsterResource" ]],
     tags.body[
         tags.h1(style="font-size: large")[ "This works." ]
     ]
])

default = VHostGreeter()
default.putChild("vhost", vResource)

application = service.Application('web-proxy')
sc = service.IServiceCollection(application)
site = appserver.NevowSite(default)
i = internet.TCPServer(8080, site)
i.setServiceParent(sc)

After modifying /etc/hosts (or C:\WINNT\system32\drivers\etc\hosts):

127.0.0.1       domain1.com
127.0.0.1       domain2.com


domain1.com works as expected. It serves static pages out of the given 
directory.

Also domain2.com:8080 works.

But domain2.com just shows an empty page.

I tested this with Opera 7.11 and IE 6.0.

The nevow server gets an GET request. There is no difference in the server 
messages
between a direct call (8080) or using it as a reverse proxy:

Opera:

domain2.com:

domain2.com:8080:

IE6.0:

domain2.com:
2004/11/07 13:07 Westeuropõische Normalzeit [HTTPChannel,3,127.0.0.1] 127.0.0.1
- - [07/Nov/2004:12:07:25 +0000] "GET / HTTP/1.1" 200 129 "-" "Mozilla/4.0 
(comp
atible; MSIE 6.0; Windows NT 5.0)"

domain2.com:8080:
2004/11/07 13:07 Westeuropõische Normalzeit [HTTPChannel,4,127.0.0.1] 127.0.0.1
- - [07/Nov/2004:12:07:46 +0000] "GET / HTTP/1.1" 200 129 "-" "Mozilla/4.0 
(comp
atible; MSIE 6.0; Windows NT 5.0)"

The twisted web server shows the following messages:

2004/11/07 13:07 Westeuropõische Normalzeit [HTTPChannel,2,127.0.0.1]

actory <twisted.web.proxy.ProxyClientFactory instance at 0x00B716E8>
2004/11/07 13:07 Westeuropõische Normalzeit [ProxyClient,client] Stopping 
factor
y <twisted.web.proxy.ProxyClientFactory instance at 0x00B716E8>

How do get the page display when requesting domain2.com?

Thanks.
