How to encrypt proxy cache

[sachin.shetty@gmail.com]

Hi,

We are testing using nginx as a file cache  in front of our app, but the
contents of the proxy cache directory are readable to any body who has
access to the machine. Is there a way to encrypt the files stored in the
proxy cache folder so that it' not exposed to the naked eye but nginx
decrypts it on the fly before serving it to the user. 

Thanks
Sachin
