Configure client failover proxy settings

Use this policy to configure alternative network proxies that the client can use if the primary network proxy fails to connect to a remote application or desktop.

When this policy is not configured, the client will use its own settings to decide whether to connect through a proxy server.

When this policy is enabled, the client will attempt a connection using an alternative proxy if connection to a primary proxy fails. The failover proxy settings operate in an identical fashion to the primary proxy settings.

If both the primary and alternative proxy fail to service the connection, selecting the "Failover to direct" check box instructs the client to attempt a final direct connection with no proxies.

Troubleshooting:
Some proxy failures can make the client appear to hang on connection. This is usually due to the proxy server reattempting the connection itself, or having a long time-out period. Depending on the network topology, it may be preferable to configure the Web Interface server to identify the currently functioning proxy, or alter the proxy server time-out settings.
