This is extremely illuminating. The key approach/idea that I was missing is this:
You can create a root web.resource.Resource() and add a child "" that handles all URLs not otherwise matched by a known child.
This is incorrect. A child of "" matches the empty path segment. Most of the time this is used to handle a URL that ends in a "/" but an empty segment is also legitimate in the middle of a URL.
I stand corrected, though somewhat confused as to how Stephen's code is working, then. My own experience does back up your statement, though.
In Nevow, you handle unmatched children by overriding locateChild(self, ctx, segments) or, in the case of a rend.Page subclass, providing a childFactory(self, ctx, name) method.
Indeed, as I discovered in implementing this. Still, Stephen's approach works fine, I was just wrong about thinking it was implemented automatically for the "" case. To make it work with a Nevow site, I created a root resource like this: class SiteRoot( object ): __implements__ = (inevow.IResource, ) isLeaf = False def __init__( self, root ): """Initialise the overall root""" self.root = root self.RPC = webservices.XMLRPCServer() def locateChild(self, ctx, segments): """Locate child, return as inevow.IResource""" if segments: if segments[0] == 'RPC': return self.RPC, segments[1:] return self.root, segments def renderHTTP( self, ctx, **named ): """Render this resource on an HTTP request""" raise ValueError( """You shouldn't be able to view this node!""" ) then wrap the SiteRoot instance in a nevow.appserver.NevowSite instance (it won't work if you try to use a twisted.web site, because that site class doesn't know how to traverse Nevow resources). You also AFAICS should not wrap the "root" in an appserver.NevowSite instance (it seems there should only be one site instance for any given web-server). So, to recap: nevow.appserver.NevowSite SiteRoot( root ) root = guard.SessionWrapper( portal.Portal( realm.YourRealm( rootResourceForNormalSite ) ) ) -- with the appropriate credential checkers registered.
