Macintosh Web servers are not as scalable and reliable as Windows or Unix servers, but they serve a purpose and allow Macintosh developers and IT professionals to stay on a platform that is comfortable and convenient to them. If you are going to run a business Web site on a Macintosh Web server, then you should look at one of the following servers.
WebSTAR is the best Web server available for the Macintosh. It includes virtual domain support, caching proxy server, a built-in Java virtual machine, and encrypted remote administration support. This server is a good choice even for enterprise-level Web sites. Its performance is not comparable to a similar Unix Web server, but it is the best choice for a Macintosh Web server.
Apache is a free, configurable Web server available for Unix, Linux, Windows, Mac OS and many other operating systems. It is one of the world's most popular Web servers and has many people working on improving it all the time. This server can be very difficult for the novice to install, but there are now companies that offer support plans and assistance to keep your sever up, running, and secure.
Zeus Web server is a highly scalable and secure Web server. The Gartner group recommends it as a viable replacement for other less-secure Web servers. It can be a lot more expensive than Apache, but for the price, you get a lot of service and functionality.
This is a pure-Tcl implementation of httpd. It supports features like CGI, SSI, authentication, image maps, and logging. You can add additional modules to get functionality like dynamic page generation, SNMP integration, and SSL. It's easy to install and configure, but doesn't have a lot of support and the security is somewhat lax.
