Pound is a wonderful tool. It does just what you want, and does it good. Well, most of the time actually. Let me present it.
Pound is made by a Swiss company named Apsis GmbH (http://www.apsis.ch/), and its purpose is to achieve 3 goals :
- reverse proxy
- load balancing
- HTTPS front-end
You don’t need to use all 3 features, but you might need it anyway. Don’t assume it can do other things : No caching, no webserver, no acceleration. Just what it’s meant for.
