When the Application Server authPassthroughEnabled property is set to true, information about the original client request (such as client IP address, SSL key size, and authenticated client certificate chain) is sent to the HTTP listeners using custom request headers. The authPassThroughEnabled property allows you to take advantage of a hardware accelerator for faster SSL authentication if you have one installed. It is easier to configure a hardware accelerator on the load balancer than on each clustered Application Server instance.
Set authPassthroughEnabled to true only on if the Application Server is behind a firewall.
Use the asadmin set command to set the authPassthroughEnabled property on the HTTP service or the individual HTTP listener. The setting for the individual HTTP listener takes precedence over the setting for the HTTP service.
To set the authPassthroughEnabled property on all HTTP/HTTPS listeners, use the following command:
asadmin set cluster-name-config.http-service.property.authPassthroughEnabled=true
To set it on an individual listener, use the following command:
asadmin set cluster-name-config.http-service.http-listener.listener-name.property.authPassthroughEnabled=true
