In case you are paranoid about people uploading 2 gig kitty-porn to DOS your server, like zamolxes, and you are running lighttpd like any sensible person (read 'me'), here's the option to restrict the max size of post requests:
server.max-request-size 104857600
would restrict it to 100 megabytes. If you need a smaller size, just ask google :)
server.max-request-size 104857600
