Consider user accounts on a system with a Web server configured to provide access to user Web areas. In general, it uses a standard directory name, such as public_html, in a users home directory. This acts as their user Web area if it exists. However, to allow the Web server to access the pages in this directory, it must have at least search (execute) access to the users home directory, read/execute access to the Web directory, and read access to any webpages in it. Consider the interaction of this requirement with the cases you discussed for the preceding problem. What are the consequences of this requirement? Note that a Web server typically executes as a special user and in a group that is not shared with most users on the system. Are there some circumstances when running such a Web service is simply not appropriate? Explain.
