It is possible to limit access to your web pages. This can be done by either limiting access to individuals at Amherst College, or by using a username and password, or both.
Access control is by directory.
It is not possible to use different types of restrictions on files in the same directory. Restrictions apply to all the files in the directory, and all subdirectories. Change to the directory that you want to restrict access to. When prompted select the type of restriction you want on the directory. If you select local access only , you're done.
