Sample Aliases and Redirects

The examples below show aliases and redirects.

• Alias:

pattern: /images

path: /Volumes/Data/imgs

If you have made a file system change but you don’t want to have to change all of

the image URLs in your HTML files, this will translate http://www.example.com/

images/boat.jpg to grab the file from /Volumes/Data/boat.jpg.

• Alias match:

pattern: ^/(.*)\.gif

path: /Library/WebServer/Documents/gifs$1.jpg

If you want all gifs to be stored in a particular directory but to be referenced from the

web server root, this will alias http://www.example.com/logo.gif to serve the file

located at /Library/WebServer/Documents/gifs/logo.gif.

• Redirect

Pattern: /webstore

Path: https://secure.example.com/webstore

This redirects all queries for webstore to the secure server.

• Redirect match:

pattern: (.*)\.jpg

path: http://imageserver.example.com$1.jpg

If you plan to host static content such as images on a new server, this will redirect all

requests for files ending in .jpg to a different server.

Additional information and other examples of aliases and redirects are available at

http://httpd.apache.org/docs/mod/mod_alias.html.
