Seems to work well. However, it doesn't seem to support ports, e.g. example.com:82 etc. Is this something that can be added?

Is there any way to redirect requests by retaining or capturing the matched patterns?

For example, redirect http://www.example.com/* to http://www.example2.com/* so that the path specified after example.com/ is copied after example2.com/

It is not so useful otherwise. :-(
