redirect directive: avoiding recursive loop
I have multiple hosts using the same IP address. How do I get the all valid urls to redirect one host. To understand what I am asking try launching your browser and enter the url http://sun.com. You'll see that the url changes to http://www.sun.com
I have tried to do this in Apache using the Redirect directive in mod_alias.
<VirtualHost *>
DocumentRoot D:\Apache\htdocs\manual\vhosts
Redirect permanent / http://www.xxx.com/
ServerName www.xxx.com
</VirtualHost>
The desired behaviour can be seen in examples 1 & 2 below. Unfortunately, my suggested configuration meets the requirement in example 1, but not example 2 because requests for www.xxx.com are redirected to themselves. The user agent cannot detect the infinite recursion.
Example 1:
Requesting the header for http://xxx.com, the user agent is advised to try location http://www.xxx.com
8< --------------------------
HEAD / HTTP/1.1
host: xxx.com
HTTP/1.1 301 Moved Permanently
Date: Tue, 16 Apr 2002 13:59:23 GMT
Server: Apache/1.3.24 (Win32)
Location: http://www.xxx.com
Content-Type: text/html; charset=iso-8859-1
------------------------- >8
Example 2:
Requesting the header for http://www.xxx.com, the user agent receives the OK.
8< --------------------------
HEAD / HTTP/1.1
host: www.xxx.com
HTTP/1.1 200 OK
Date: Tue, 16 Apr 2002 13:53:04 GMT
Server: Apache/1.3.19 (Unix) tomcat/1.0 PHP/4.0.5

Try this:
NameVirtualHost *
<VirtualHost *>
ServerName doesnt.matter.catches.everything.except.www.xxx.com
Redirect permanent / http://www.xxx.com/
</VirtualHost>
<VirtualHost *>
ServerName www.xxx.com
DocumentRoot D:/Apache/htdocs/manual/vhosts/
</VirtualHost>
