BIS on UNIX supports the following machine environment:
The Apache 2.4 web server must be installed. Apache normally listens for HTTP requests on port 80 and for HTTPS requests 443, and when properly configured, routes BIS requests to the BIS Request Handler. On many versions of UNIX, Apache is available in a binary format that may be installed from the operating system's installation media or downloaded from the operating system's supplier. In order for Apache to use the BIS Request Handler, it must have shared object support. If downloading from a binary installation, make sure that it is configured with shared object support (mod_xbis_so). After downloading the binary installation, follow the supplier's instructions for installing Apache. If your system does not have Apache installed, or you wish to download and install the latest version, go to http://httpd.apache.org for more information.
