The full request URI will be forwarded to the serving container in the `X-Original-URI` header.
When you want to forward many paths to the same container you can set the variable using a regular expresion. For example VIRTUAL_PATH="~^/(path1|path2)" will answer to requests that start with /path1 or /path2.
### Multiple Networks
With the addition of [overlay networking](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) in Docker 1.9, your `nginx-proxy` container may need to connect to backend containers on multiple networks. By default, if you don't pass the `--net` flag when your `nginx-proxy` container is created, it will only be attached to the default `bridge` network. This means that it will not be able to connect to containers on networks other than `bridge`.
