Apache Reference: mod_alias, Redirect

Redirect

Redirect URL Prefix to External Resource
Syntax: Redirect [status] url-prefix redirect-prefix
Example: Redirect /image http://image.foo.dom/
Since: Apache 1.0

This directive is similar to Alias in that all URLs starting with url-prefix use redirect-prefix as a substitution,, except that redirect-prefix must be an absolute URL. The resulting HTTP redirect is sent back to the client. The optional status argument can be used to return particular HTTP status codes: permanent returns a permanent redirect status (301) indicating that the resource has moved permanently; temp returns a temporary redirect status (302, the default); seeother returns a status (303) indicating that the resource has been replaced; or gone returns a status (410) indicating that the resource has been permanently removed.

When this status is used, the redirect-prefix argument should be omitted. Other status codes can be returned by giving the numeric status code as the value of status. If the status is between 300 and 399, the redirect-prefix argument must be present; otherwise, omit it.
