2 Configure the IP address to use when establishing connections with Web servers:
Cluster Member: (Available only if the Access Gateway is a member of a cluster.) Select the
server you want to configure from the list of servers. Only the value of the Make Outbound
Connection Using option applies to the selected server.
Make Outbound Connection Using: (Access Gateway Appliance) Specifies which IP
address the proxy service should use when establishing connections with the back-end Web
servers.
3 (Access Gateway Appliance) Select how the Web servers should be contacted when multiple
Web servers are available. Select one of the following for the Policy for Multiple Destination
IP Addresses option:
Simple Failover: Allows the next available Web server in the group to be contacted when
the first server in the list is no longer available.
Round Robin: Moves in order through the list of Web servers, allowing each to service
requests before starting at the beginning of the list for a second group of requests.
4 Select Enable Persistent Connections to allow the Access Gateway to establish a persistent
HTTP connection between the Access Gateway and the Web server. Usually, HTTP
connections service only one request and response sequence. A persistent connection allows
multiple requests to be serviced before the connection is closed.
This option is enabled by default.
5 To modify the connection timeouts between the Access Gateway and the Web servers,
configure the following fields:
Data Read Timeout: Determines when an unresponsive connection is closed. When
exchanging data, if an expected response from the connected device is not received within this
amount of time, the connection is closed. This value might need to be increased for slow or
congested network links. The value can be set from 1 to 3600 seconds (1 hour). The default is
120 seconds (2 minutes).
Idle Timeout: Determines when an idle connection is closed. If no application data is
exchanged over a connection for this amount of time, the connection is closed. This value
limits how long an idle persistent connection is kept open. This setting is a compromise
between freeing resources to allow additional inbound connections, and keeping connections
established so that new connections from the same device do not need to be re-established. The
value can be set from 1 to 1800 seconds (30 minutes). The default is 180 seconds (3 minutes).
