WordPress MU

is caching turned on in the WPMU version of MagpieRSS by default? if so, how often does it get an updated version?

Looks like it is:

http://trac.mu.wordpress.org/browser/trunk/wp-includes/rss.php#L624

define('MAGPIE_CACHE_ON', 1);
define('MAGPIE_CACHE_AGE', 60*60); // one hour

From looking at the code in the area, it looks like you can define this elsewhere (maybe in sunrise.php?) if you;re trying to override this.

one hour should work fine. thanks for the response!

Not a problem.

You may want to check the rss widgets and see if any other time check is being done.

edit: A quick google search doesn't pull up any mention of the time delay that I can find. That;s kind of weird.

does this mean the dashboard feeds get cached for 1 hour?
are the settings also being cached? just wondering as I have changed the number of items to display and it still shows the old number...
sorry if this is off topic :-(

I'm not in a position to check but I do remember that those feeds on the dashboard use the fetch_rss function which is the one used within magpie so I'm going to say yes but that that answer with a grain of salt.
