[ee122] resolving filesnames and directories

[Merry Choi]

Just wanted to make sure I'm interpreting these steps correctly.

If the file requested does not have an extension you can assume it is a
request for a directory. You first append /index.html to see if that
directory has an index.html file. If yes, then you send the index.html file.
If not, then you perform and ls and send the directory contents. Yes?
(Please be yes. :)
