The protocol used by a proxy-based firewall.
Possible ValuesNONE, TUNNEL, SOCKS4, SOCKS5
This property specifies the protocol that the driver will use to tunnel traffic through the FirewallServer proxy. Note that by default, the driver connects to the system proxy; to disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.
|TUNNEL||80||When this is set, the driver opens a connection to Google Spanner and traffic flows back and forth through the proxy.|
|SOCKS4||1080||When this is set, the driver sends data through the SOCKS 4 proxy specified by FirewallServer and FirewallPort and passes the FirewallUser value to the proxy, which determines if the connection request should be granted.|
|SOCKS5||1080||When this is set, the driver sends data through the SOCKS 5 proxy specified by FirewallServer and FirewallPort. If your proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.|
