IBM HTTP Server

Edit online

The Web communication for the ECM system was managed via an IBM® HTTP Server (IHS).

The IHS received client requests and forwarded them to the ICN application. Components of ICN were mapped to the IHS to manage the HTTP traffic.

The IHS also act as a load balancer, if there are more than one WAS cluster members available.
