Rails: how to get the current host, or build a URL with it?
I need to use the host to build a URL with a different port.

For example, if the host is example.com, I need to generate a URL like http://example.com:8080/

I need it to be portable, so when I'm in my local enviroment it shows http://localhost:8080/ instead.

Any ideas?
