But that's fine. As I said, just substitute the example path with something you have or can have on your server. What about "classes" and then put a .htaccess and .htpasswd thing in that directory to avoid people moving their browser into that directory, but still have a password, so you personally can browse your classes.
There is no reason this should not work.
Oh, if you are not too familiar with password protection in apache, then have a read of this:
