Could you tell me how to configure /etc/htdig/htdig.conf

start url: <point to website stored locally on hard drive>

So I can index a website that is in a local directory. Say I have a directory called "/home/sam/directory" that I want to index. It is all html files pointing to each other. How do I specify that, exactly, in the

start url: statement.

I have tried:

start url: http://127.0.0.1/home/sam/directory
start url: http://localhost/home/sam/directory
start url: http://127.0.0.1/home/sam/directory/index.htm
start url: http://127.0.0.1/=/home/sam/directory
start url: file:///home/sam/directory

htdig keeps telling me unknown host, or unable to establish a connection. I opened a listening connection with nc on port 80. I think my syntax is wrong in the start url: statement. Would you please help me out with this?
