Well, it's recommended specifically because it does client caching (and 
includes a few special features geared to caching controller actions, such 
as more easily making the cached value specific to the requested language, 
user agent, etc.). But if you don't want client caching, there's nothing 
wrong with the more general @cache decorator.

Thanks! I somehow was under the impression that the old way of using cache 
is somehow deprecated. I re-read the book again, and there is just a 
statement "We recommend @cache.action 

 starting 
from web2py > 2.4.6". But since this is not possible with cache.action, I 
will try using the cache.ram.

Cheers,
Krzysztof.

Looking at the code, it does not appear it is possible to turn off client 
side caching when using @cache.action. However, if you don't want 
client-side caching, you might as well just use @cache.ram.
