Simple *nix tool for listening to HTTP requests and logging the request data

Question

What's a simple, easy-to-use *nix tool that will listen to requests on a given port and log the request header and body?

Answer 1

How about netcat?

sudo nc -l 80

Update: Here's what I see when I send a request through a browser.

[~]$ sudo nc -l 80
