Reverse proxying to mythweb

Here's my proxy configuration:
<VirtualHost *:80>
    ServerAdmin david@thekramers.net
    ServerName  geekwith.me
    ServerAlias www.geekwith.me

    ErrorLog /var/log/apache2/geekwith.me-error_log
    CustomLog /var/log/apache2/geekwith.me-access_log combined


    ProxyPass / http://10.1.10.150/
    ProxyPassReverse / http://10.1.10.150/
</VirtualHost>


I don't know what mechanism does it, but when I go to http://10.1.10.150/ it redirects to http://10.1.10.150/mythweb to get to that application.  When I go through this proxy by going to htp://www.geekwith.me, it rewrites it as www.geekwith.me/mythwebmythweb  (yes twice).  Dunno how I broke that.
