I have a domain say <http://www.testexample.com>. When I login to <http://www.testexample.com> and come back to <http://testexample.com> in browser; the logged in user information is not displayed.  

I know that the both of the above are treated differently and hence it is not retaining the session for <http://www.testexample.com> while accessing <http://testexample.com>. 

Please let me know if cakephp has a way to do a match on the TLD. So whenever I type <http://testexample.com> it should take session for <http://www.testexample.com> 

I am using the following code to redirect from one URL to the other 

```
RewriteCond %{HTTPS} off   
RewriteCond %{HTTP_HOST} ps6309 [NC]   
RewriteRule ps6309.domain.co.in [L,R=301]

```

this is on my local test machine. This works sometimes and sometimes doesn't.  

Also I have added the rewritelog directive to my httpd.conf file. 
But the log file is not getting updated. 
Please let me know if anyone has any pointers to this.
