Clearing Symfony cache for another application

Question

I would like to clear my frontend application\'s cache from an action in my backend application.

How can I achieve this?

Answer 1

If anyone is looking for clearing one cache item (one page):

sfContext::switchTo('frontend');
sfContext::getInstance()->getViewCacheManager()->remove("module/action?¶m1=value1¶m2=value2","THE-DOMAIN-OF-YOUR-FRONTEND-APPLICATION-IF-U-USE-IT-IN-CACHE-KEYS");
sfContext::switchTo('backend');
