Yawn offers you a way to specify a "shorthand" for frequently used paths. In the httpd.cfg file you can specify aliases for directories, as well as Redirect directives, which allow you to tell the browser to look elsewhere for a document that has moved. A special kind of an alias is the ScriptAlias - a directory in which external scripts are stored.

To create an alias for a directory, you need to add an Alias directive to the configuration file - one directive for one alias, with as many of them as you wish:

Alias    fakename  realname, e.g.
Alias    /images  http://your.site/images
Alias    /software  sys:users/artur/software

Using the directive:

ScriptAlias    fakename   realname, e.g.
ScriptAlias    /cgi-bin  sys:system/httpd/cgi-bin

allows you to shorten the name you have to type while creating a file referencing external programs, and also to restrict the presence of such programs to the directories specified in the configuration file.

Redirecting is useful when a given resorce is not available under its original name or at its original location, or e.g. when you want to point to a different site without entering the full URL each time. By using a directive like:

Redirect    fakename   url, e.g.
Redirect    /cgi-bin/finger  http://www.lublin.pl/cgi-bin/finger/finger

You can tell the browser to find the requested item at another place. This is done by returning a Location HTTP header with the 304 error message "Moved". If your browser cannot recognize the Location header, you will stil be given an HTML file with a link to the requested resource.
