Reverse proxying with Apache

I had a network-attached webcam that I want to reverse proxy through apache to take advantage of its https support. The camera is at 192.168.1.253. Here are the steps I took:

# a2enmod proxy proxy_http
# vi /etc/apache2/sites-available/webcam-proxy
# cat /etc/apache2/sites-available/webcam-proxy
ProxyRequests Off

<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyPass /webcam http://192.168.1.253/
# a2ensite webcam-proxy
# /etc/init.d/apache2 reload
