Open Stack

Hi all, I just set up keystone with apache(2.2.15) and mod_wsgi. It runs 
perfectly.
But when I tested my own application, it threw an exception of 404 Not 
Found, because it accessed the url: http://192.168.242.10:/35357/v2.0

And I curl to get keystone versions, the result is weird.

Here's what keystone+apache shows:
# curl -i -X GET http://192.168.242.10:35357/ -H 
"Content-Type:application/json"
