Dhttpd just serve static pages. the only add-ons is the ability to lookup hosts for logging purposes. for production website, something like thttpd would be a better bet.

doesn't run external programs (no cgi-bin support), so this webserver cannot be easily hacked:
* does not need a permanent ip address.
* memory efficient.
* low profile.
* quick.
* just transfers files.
* can be run from a user account on high ports.
* no configuration necessary. it just works.
