[Twisted-web] Re: Serving files from many web-servers thru one central web-server

[Thomas Weholt]

Oh, darn!! Forgot all about this when I started my project. I've read
thru most of the docs I've  found so far, but I'm still somewhat
clueless. Can anybody provide a simple example of how to do this,
preferrably without using the examples in
http://twistedmatrix.com/documents/current/howto/using-twistedweb#auto19.
I'm hooking a xmlrpc-handler and a UDP listener into it as well and
find the good ol'

site = server.Site(MyResource())
reactor.listenTCP(8080, site)
reactor.run()

way of doing it better than mktap etc. Feel like I got more control
doing it the manual way.

Anyhow, thanks for your input so far. I just love Twisted !! :-)

Best regards,
Thomas
