How to do Virtual Hosting

CHerryPy has a built-in dispatcher for supporting Virtual Hosts. See:

• http://groups.google.com/group/cherrypy-users/browse_thread/thread/f393540fe278e54d
• http://www.cherrypy.org/changeset/1655

Put simply this means you can develop an application that can serve different parts of itself for different virtual hosts. For example, say you have an application mounted at / on http://domain.com/ you could map:

• http://foo.domain.com/ -> /foo
• http://bar.domain.com/ -> /bar

Example

conf.ini

[global]
server.socket_port = 8000
server.thread_pool = 10

vhosts.py

#!/usr/bin/env python

import cherrypy
from cherrypy import expose

class Root(object):

   @expose
   def index(self):
      return "I am the main vhost"

class Foo(object):

   @expose
   def index(self):
      return "I am foo."

class Bar(object):

   @expose
   def index(self):
      return "I am bar."

def main():
   cherrypy.config.update("conf.ini")

   conf = {
         "/": {
            "request.dispatch": cherrypy.dispatch.VirtualHost(
               **{
                  "foo.domain.com:8000": "/foo",
                  "bar.domain.com:8000": "/bar"
                  }
               )
            }
         }

   root = Root()
   root.foo = Foo()
   root.bar = Bar()
   cherrypy.tree.mount(root, "/", conf)

   cherrypy.server.quickstart()
   cherrypy.engine.start()

if __name__ == "__main__":
   main()
