Subject svn commit: r432999 - in /httpd/httpd/branches/2.0.x/docs/manual/mod: mod_alias.html.en mod_alias.xml
Date Sun, 20 Aug 2006 18:20:12 GMT
Author: slive
Date: Sun Aug 20 11:20:11 2006
New Revision: 432999

URL: http://svn.apache.org/viewvc?rev=432999&view=rev
Log:
Backport:
Make it clear that url-path is always case-sensitive.
Provide an example of using a regex to make it case-insensitive.
Make it clear that ScriptAlias is only used when you want
BOTH mapping and script-designation.

(Plus the description of Redirect)
