This is a quick blog for me to remember how to do a proxy in apache:
<VirtualHost *:80>
ServerName www.someurl.com
ServerAlias www.someurl.com
ServerAdmin someone@someurl.com
ProxyPreserveHost On
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://999.888.777.666:8080/
ProxyPassReverse / http://999.888.777.666:8080/
</VirtualHost>
