Last Modified header issue in support RSS feed
|Reported by:||Rarst||Owned by:|
From personal experience support feeds work horribly in feed reader services. I discovered the reply from week (!) ago still hadn't appeared in feedly for me (just as it was often stuck for days in google reader in the past) and looked at feed more closely.
As of now my feed http://wordpress.org/support/rss/view/plugin-contributor/Rarst
Has header Last-Modified: Wed, 17 Jul 2013 16:41:02 GMT
While actual last message in it was at Mon, 29 Jul 2013 14:20:26 +0000 and the date from header corresponds to four messages earlier.
This is very likely to cause incorrect 304 Not Modified responses to feed readers and have them stuck if they are not refreshing aggressively.
