Cache Control

Cache controller

This site uses various cache systems for speed and a bytecode accelerator for PHP.

Information

Due to caching, sometimes changes in movie texts / movie categories / submission edits do not become immediately visible to all of the audience of the site.

Here is a list of some of the caching employed:

Wiki pages for non logged in users Entire page is cached to file, and is updated hourly by a bot which deletes all pages which are older than 18 hours. This cache can also be cleared by TASVideoAgent in the IRC channel[1]. Note, that movie publications, as well as text edits to wiki pages will delete old pages immediately.
Movie module For 5 minutes.
Submission pages For 5 minutes.
Submission list For 5 minutes. However different levels of users cache different lists.
Topic feed (news) For 1 hour.
Move change log For 15 minutes.
Front page submission list For 15 minutes.
SVN log module For 15 minutes.
RSS log module For 15 minutes.
Awards Until PHP is restarted.
Streaming URLs Until PHP is restarted.
Standard RSS Feeds Hourly
Per Movie RSS Feeds Checked hourly for feeds older than 18 hours and updated. This cache can also be cleared by TASVideoAgent in the IRC channel[1].
