[wp-hackers] Clearing Feed Cache?

[Potkanski, Jason]

Is there a way to set this up so one type of feed has a shorter cache lifetime?

Say I use xml sitemaps and want the sitemap feed to be 5 minutes but the rss, rss2, atom etc as 12 hours.

add_filter( 'wp_feed_cache_transient_lifetime', create_function( '$a',
'return 1800;' ) );

use this filter to set a new time for the cache.
