Paths and Permissions (posted 28 September 2004)
In this class we'll tackle two concepts that are central to web publishing.
The first is file addressing--relative versus absolute paths. This has its roots in the Unix operating system, but is also important in HTML, particularly when building complex sites. You'll learn the difference between relative and absolute addresses, and how to construct relative paths.
The second is permissions--how to allow selective access to files and directories for reading, writing, and execution.
