The wwService is a web service pass-through wrapper for ww.dll. The service enables the pages of the web site to be on a different computer (different site, even) than ww.dll. Typically, this would be installed on a server at a local site along with ww.dll. When using wwService, clients should be using IP addresses to define the location of the ww.dll rather than a computer name.

If the Internet is to be used as transport, then encryption is enabled (with matching pass phrases) on both wwService and the web site hosting the web pages. The encryption capability in communications between wwService and the web site eliminates the need for an SSL certificate on the wwService computer. For more information on how this is done, see Secure web service.
