Useful tip:
By default FlyingAnt will treat the following files as default index files (ie. it will open them if they exist when an url pointing to a folder they reside in is submitted)
index.html
index.htm
index.php
index.cgi
To change these there is a a config file option "index_files" that can be used in the following format
index_files index.html index.htm index.shtml
