Load Balancing WCF - basicHttpBinding

  • Article

Load balancing WCF with basicHttpBinding can be done using the keepAliveEnabled property when there is connection reuse. Basically this property when enabled, enables a client to maintain a persistent connection with the service and gives enhanced throughput with connection reuse with multiple messages. But in a load balanced farm we cannot have a client strongly associated with a server and so need to disable this property.

This can be accessed through a custom binding as follows.

        <bindings>

            <customBinding>

                <binding name="NewBinding0">

                    <textMessageEncoding />

                    <httpTransport keepAliveEnabled="false" />

                </binding>

            </customBinding>

        </bindings>
