  *
  * Set a custom cache-control header, usually being "private" or "public";
  * The max_age parameter controls how long the cache entry is valid on the client side.
  * 
  * Expects a string parameter containing the primary cache control setting.
  * Additionally accepts an int parameter specifying the max-age setting.
+ * Accepts an optional third bool parameter indicating whether the cache
+ * must be revalidated every request.
  * 
  * Returns TRUE on success, or FALSE if control does not match one of
  * "public" , "private" or "no-cache".
