# VirtualHostResource

This resource will allow you to do multihoming. This technic is a way to host multiple logical web servers on the same physical process. Jigsaw supports only `Host` header based virtual hosting, which does not consume IP addresses.

As for other resources that are suposed to be the root resource of your server, you should be very cautious when using that kind of resource. In particular make sure the followup attribute is set to a resource that will export the Admin directory.

Each child of the VirualHostResource must be named under the host name it will serve. If you have a machine A with names `name.foo.com` and `alias.foo.com`, and if the server is running on port `8001`, then requests prefixed by `http://name.foo.com:8001/` will be dispatched to the child resource of the virtual host resource named `name.foo.com:8001` and requests prefixed by `http://alias.foo.com:8001` to child resource `alias.foo.com:8001`.

Warning: Unless you understand what you are doing, children of that resources should only be either MirrorDirectory or PassDirectory instances.
