Exactly as Dougal suggested in the link you provided. [0]

While the filter being leveraged there, wp_feed_cache_transient_lifetime, is
not new in 3.0, the $url argument is passed as context for the first time in
3.0. You're not passing a URL; you're filtering the cache time based on the
URL that you're given. The function in that post remains both relevant and
correct.
