read CAREFULLY http://web2py.com/books/default/chapter/29/04/the-core#cache
.
Unfortunately (?) web2py's cache isn't "the usual" cache object, as it's
designed to store indefinitely values that do not expire automatically.
Basically time_expire vouches to either fetch the stored value or to update
the one already in cache.
time_expire=None forces the retrieval of the stored value, without updating
it, so you MAY use it for your usecase.
NB: The redis backend needs to adhere to the same API web2py has, but
leverages redis evictions postponing a bit the real expiration.
