Even more confused.... I commented out my entire default file except server {} and IT STILL LOADS the index.php file WITH the PHP fast CGI??!!! So basically my default file was doing NOTHING.

My current file:
CAPS ARE MY PRIVATE VALUES with the EXEPCTION of SCRIPT_FILENAME which appears to be a constant or variable

server {
listen 90;
# server_name SERVER
# access_log PATH_TO_LOG
# error_log PATH_TO_LOG
# root /var/www;
# index index.php index.html
# rewrite_log on;
# if ($request_ur ~* ^(/welcome(/index)?|index(.php)/?$))
# {
# rewrite ^(.*)$ / permanent;
# }
# if ($request_uri ~* index/?$)
# {
# rewrite ^/(.*)/index?$ /$1 permanent;
# }
# if (!-d $request_filename)
# {
# #some sites use * and some use + what is the difference?
# rewrite ^/(.+)/$ /$1 permanent;
# }
# if (!-d $request_uri ~* ^/system)
# {
# rewrite ^/(.*)$ /index.php?/$1 last;
# }
# if (!-e $request_filename)
# {
# rewrite ^/$ index.php/;
# rewrite ^(/.*)$ /index.php/$1 last;
# }
# error_page 404 /index.php;
#location ~ \.php$

}
