Aliases are a way of mapping an incoming request from one location to another. An alias can change the document, directory, or even server of a requested URL. Aliases are also used to indicate which file system a particular URL should be served out of.

When an alias is found in a URL, the alias's value is substituted in place of the alias. The alias must match the user's URL from the beginning. If the alias matches a string in the middle of the URL, no substitution is performed.


A string that will be replaced in a URL if it matches the beginning of the URL. Because it must match in the beginning, a leading slash must be used.
