Trigger Authcache Reload on Field Change for Drupal Commerce Products I activated authcache and the cache system is working well.
When i change the price for a product the page is read from the cache.
How can i trigger to reload the page from database if one specific field (price field for example) is changed?

Information on my installation:

I have installed Drupal Core 7.37 , Commerce 7.x-1.11. and AuthCache 7.x-2.0-beta5.
Authcache comes with an integration module for the Cache Expiration project. See also the Authcache 2 tuning guide - integrate with Cache Expiration module.

It might get tricky to find all pages where a particular product/price is displayed due to the separation of products and display nodes in commerce. Depending on how frequent prices are changed, you might consider nuking the whole cache, e.g. using a combination of Rules and the Cache Actions module.
