Is it somehow possible to define a fallback repository in the WQS web app that will be used in case the standard repository is not available? We are planning to have the following setup: One Alfresco instance behind the firewall uses Transfer Service to replicate its content to two public Alfresco instances. We will then have at least two instances of the WQS web app that will connect to these public Alfresco instances. If one of these Alfresco instances goes down the WQS web app instances should automatically use the remaining Alfresco instance.
