如何在Openshift中清除缓存

I am developing a iphone app and I am using Openshift as web services for my app. My app will call the web services every 10 seconds however my app often get the old responses from web service. I don't understand why but I think this server was cached. Is this right? Can you please help me step by steps so that I can clear cache my Openshift server? Thanks

Openshift PHP cartridges use a cache. You can disable it with rhc using this command:

rhc env-set OPENSHIFT_PHP_APC_ENABLED=false --app <app>

Hope that helps...
