For releases before V.6.2.3, HTTP was only used to transfer static content such as help files from the embedded HTTP server in IBM Tivoli Monitoring, or for single sign-on using the embedded HTTP server in the WAS component. As of version 6.2.3 and higher, the Tivoli Enterprise Portal Server installation contains a required IBM HTTP Server front end for all HTTP and HTTPS traffic.
