Raymond,

Is the mythtv.org server running MediaWiki with mod_disk_cache?

If so, is the stale caching issue the same as that described in the
article (and fixed with its accompanying patch) at
http://blogs.testbit.eu/timj/2011/02/09/using-mod_disk_cache-with-mediawiki/
?

I currently see:

The 'Expires' and 'Cache-Control' header contents seem to match those
described in the article above, resulting in caching of stale pages
unless forcefully purged.

Cheers,
Nick
