Local Host Cache

Local Host Cache enables connection brokering operations in a Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) deployment to continue when a Cloud Connector cannot communicate with Citrix Cloud. Local Host Cache engages when the network connection is lost for 60 seconds.

With Local Host Cache, users who are connected when an outage occurs can continue working uninterrupted. Reconnections and new connections experience minimal connection delays.

Important:

Local Host Cache requires a customer-deployed on-premises StoreFront as part of the deployment. You must add all Cloud Connectors that have (or can have) VDAs registered with them to the StoreFront as Delivery Controllers. A Cloud Connector that is not added to the StoreFront cannot transition to outage mode, which might result in user launch failures.

For deployments with no on-premises StoreFront, use the service continuity Citrix workspace platform feature to allow users to connect to resources during outages. For more information, see Service continuity.

Data content

Local Host Cache includes the following information, which is a subset of the information in the main database:

• Identities of users and groups who are assigned rights to resources published from the site.
• Identities of users who are currently using, or who have recently used, published resources from the site.
• Identities of VDA machines (including Remote PC Access machines) configured in the site.
• Identities (names and IP addresses) of client Citrix Workspace app machines being actively used to connect to published resources.

It also contains information for currently active connections that were established while the main database was unavailable:

• Results of any client machine endpoint analysis performed by Citrix Workspace app.
• Identities of infrastructure machines (such as Citrix Gateway and StoreFront servers) involved with the site.
• Dates, times, and types of recent activity by users.
