Abstract: For many years IBM has provided an HTTP Server for the z/OS operating system. That HTTP Server was based on an earlier HTTP Server called the “Domino Go Webserver,” and for that reason it is sometimes referred to informally as “DGW.” More often it was referred to as “the HTTP Server” or “IHS.” This HTTP Server has been and currently is delivered as part of the base operating system. It is currently at the V5R3 level..

In 2006 IBM released a different HTTP Server for z/OS. This was based on the open source Apache web server, and extended to be z/OS-aware. This web server is known as the “IBM HTTP Server for z/OS Powered by Apache.” That is presently at Version V6R1. Future functional enhancements will be made to this HTTP Server on z/OS. The purpose of this document is to make you aware of this new IBM HTTP Server for z/OS and help you understand how to acquire it and use it.
