- Never caches anything.
- Doesn't limit bandwidth, request time or simultaneous connections.
- All header names are converted lowercase so they don't vary between browsers/clients.
- Very low memory overhead when processing even the largest of requests.
- Temp file usage and threading model are easily cutomized.
- Persistent connections (Connection “keep-alive”) support allowing multiple requests to be served over a single socket connection.
