title: Does cache invalidation on dispatcher automatically happen when we activate a page in CQ author instance?
body: <p>Hi have a small requirement related to a CQ page content modification and activation. However, I need to understand some basics before I work upon it. When a CQ author modifies a page content in author instance and activates it, it will be replicated into publish instance. However, will the cache invalidation for that page happen on dispatcher automatically after the page is published or do we have to manually clear the dispatcher cache by using some code?</p>
  
  <p>help me understand this process</p>
