[Plugin: WP Super Cache] Where supercache configuration is located?

Hi,

I have a WordPress MU installation with WP Super Cache enabled on four servers accessing one database. Sometimes I have to disable the Supercache plugin, and for this I have to go to each web server and disable on the wp administration panel. For this behavior, I assume that Supercache writes it’s “state” (on, half-on or off) in other location besides database?

Could someone tell me where supercache set its state? I’m in need for a way to “automate” these changes ??

Thanks.
