David's explanation was correct, but I tend to expect long-standing URLs to continue to work. With that in mind: Twisted's philosophy in this regard is to provide simple interfaces so that you can write your own "glue" resources criteria as you see fit. Since I was bored and stuck in a train station while I was reading this message, here's a quick "left/right" switch for resources. Toooootally untested, not even run.
The way you'd use it in your program is similar to dreid's .tac example:
segments[-1].split('.')[-1] in ('php', 'js', 'css'),
ReverseProxyResource('localhost', 8080, '/'))
And here's the implementation:
from zope.interface import implements
from twisted.web2 import resource, iweb
I am a resource that switches between two alternative resource hierarchies
depending on a callable.
def __init__(self, switch, left, right):
Create a switching resource.
@param switch: A one-argument callable that takes a sequence of
segments and returns False to divert to the left resource and True to
divert to the right.
@param left: An IResource provider to be used when 'switch' returns
@param right: An IResource provider to be used when 'switch' returns
self.switch = switch
self.left = left
self.right = right
def locateChild(self, request, segments):
res = self.right
res = self.left
return res.locateChild(request, segments)
def render(self, request):
