Apache provides a very powerful module, mod_rewrite, that allows virtually unlimited URL manipulation capabilities using regular expressions. Due to its complexity, it is outside the scope of this book other than specific references or examples in other chapters. It is mentioned here so you are aware of its existence if you reach the limits of what Redirect, ErrorDocument, and Alias directives can do. You can learn more about mod_rewrite at http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html. |
