is it cloaking or black hats?

someone knows about cloaking or black hats?. Please visit this http://www.apolloendo.com/recommended_health_resouces.html. when you will check cache date of this url, The google cached page shows for home but not same pages, Is there used cloaking trick?

 

I think it's not cloaking but it may be a redirection....

 

thanks for reply

 

if it is redirection, why is not showing home for which has been redirected?

 

the url you gave is nothing wrong, and I cannot find google cache it, google only cache the homepage

 

Cloaking is blackhat
