Pothi,
Thanks for the reply. I took a look at the page cache and it uses _gzip so I thought I would implement that through nginx along with using the W3 method of using rewrite to serve out the .gzip version. The page_enhanced cache method is quite clever because it uses parameters that are available so that you can rewrite without even using php.
Here is the Nginx conf just in case someone finds it useful. For now Nginx is serving out page and minimize files and in gzip if the browser supports it.

}Most likely in the future I will just let Apache serve out the page cached files so that I can track them in the Apache server logs.
