Description

DefaultContentUrlCache is using IObjectInstanceCache and not ISynchronizedObjectInstanceCache. Therefore, URLs are not removed from all instances in a load-balanced setup.

Reported from Content url caching not invalidating on synchronized sites (episerver.com)

How to reproduce:

  • Set up a load-balance environment with remote events.
  • Upload an asset.
  • Render link to asset in a view.
  • Access the view from both nodes and click the link.
  • Change the URL to the asset from one of the nodes.
  • Refresh the view on the other node and click the link.
