Dispatch.fcgi + lighttpd upload files


as i’m aware that there are not too many out there still using
dispatch.fcgi && lighttpd (rather moving to mongrels && nginx ) , i’ll
try to make this simple:

how do i limit a file upload size in lighttpd? am i supposed to do this
via the app? i’ve racked the internet for a while now, and my mind is
heavy and stumped.

i’m running dispatch.fcgi && lighttpd as the web-server.

any help or references would be greatly appreciated.
