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]. |
