Automatically delete cache for WP Super Cache ?

Hi everyone,

I am using the WP Super Cache plugin for a website which has a lot of traffic, and it works perfectly.

However, there are posts several times a day, from different authors, and only one user (admin) can clear the cache. So when authors write or mofify articles, is it possible to have a functionnality which automatically clear cache files ? Or something like a cron job which delete files each 2 hours.

If someone could help me, it will be glad.

Thx guys !
