About HomeDoor

The HomeDoor Multi-domain Web Service Manager is a unique product from Open Door Networks, Inc. Until HomeDoor, a Macintosh-based Web server could not act as multiple virtual Web servers, each with a name of the form http://www.companyX.com. Although you could assign multiple domain names to a Mac-based Web server, accessing that server through each of those domain names would always bring the browser to the actual server. There was no way to indicate that, for instance, www.companyX.com should point to company X's site and www.companyY.com should bring up company Y's site. Every Mac server could provide independent service for only one domain name.

HomeDoor, in concert with your domain name server (DNS), enables a single Mac-based Web server to act as a large number of virtual Web servers. HomeDoor requires no modification to the Web server itself.

HomeDoor not only serves home pages, but also enables the creation of "virtual domains." The principal component of a virtual domain is a virtual Web server. A virtual Web server is a directory within an actual Web server that appears to the outside world as if it is a complete Web server in and of itself. A virtual Web server not only supports home pages of the form http://www.companyX.com, but also files and directories within the virtual server of the form http://www.companyX.com/file-or-directory. HomeDoor enables any Web server to act as a large number of virtual Web servers.

Version 2.0 provides a significant increase in HomeDoor's functionality by including a new "host field mapping" method for implementing multi-domain Web services, along with the original "browser-independent redirection" method.

Browser-independent redirection is implemented through an extension, host field mapping through a WebSTAR plug-in, and both are administrated with HomeDoor Admin. Their relationship is illustrated in Figure 1.

The advantages and disadvantages of each method are presented in the Method Tradeoffs section of the HomeDoor Reference. Using HomeDoor Admin, a Webmaster can choose methods on a domain-by-domain basis.

An additional feature of HomeDoor is that browser-independent redirection can log accesses to pages within any virtual domain which it supports. The log, which only includes accesses made through HomeDoor, provides a succinct listing of top-level accesses to pages within HomeDoor's virtual domains.

 

About HomeDoor Lite

HomeDoor is also available in a Lite version, which is identical to the full version except that it only supports 8 virtual Web servers using redirection (vs. 256 for the full version). Both have no limit on the number of virtual Web servers supported using host field mapping.
