File permissions.

1. Always make sure your folders are given 755 permissions (with index.html file) OR 711 permissions. 711 gives Access denied error.

2. Most of the cgi scripts that run under your cgi-bin needs to be chmoded 755 to make them world executable.

3. Some cgi scripts need to chmod 777 for the folders. This is because the server needs permission to write on your files. For example you have a membership form. Your visitor fills the form. When the form is submitted by the user, the script process the data. And writes and saves the user info on your database files. So in this case you have to keep 777 permissions to some cgi folders.

Usually cgi-bin will be secured by your server host. So no need to worry about this 777 permissions of certain folders where you have to set 777.
