Symptom
When clients try to view a web page on your server with a URL that specifies a file, or contains a directory name, that corresponds to an alias file on your server, the page will not load.
Solution
Use a symlink instead of an alias. A symlink is similar to an alias and will be resolved to the original file or directory by both the Finder and the web server. You can create a symlink in the Terminal by using the command:
ln -s original_filename link_name
For more information, refer to the man page for the ln command by using the command:
man ln
