SRE-http

SRE-http is a highly configurable http/1.1 web server for OS/2. With advanced features such as remote configuration, virtual hosts, caching and SSI; SRE-http is powerful enough for technically proficient administrators, but simple enough to be maintained by non-technical users. In addition, the Rexx based GoServe API (as augmented by SRE-http's numerous extensions) offers significant development advantages when creating web based applications, and when otherwise crafting a customized and enhanced web site.

To use the SRE-http web server, you will need GoServe (a free, IBM EWS, OS/2 Internet server).
