12.6 summary

Web servers and browsers communicate using HTTP, Hypertext transfer Protocol, a simple but
effective language for requesting and transmitting data over a network. Thus, you’ll sometimes
hear web servers referred to as HTTP servers. Web servers come in various shapes and sizes.
The Apache Web server, for those of you who haven’t heard of it, is arguably the most popular
Web server in use on the Internet today. While Microsoft contends that its Internet Information
Server (IIS) is making huge gains, it’s still struggling in many ways against Apache. Apache is
configured by the files in the conf subdirectory. These are the same files used to configure the
Unix version, but there are a few different directives for Apache on Windows. See the directive
index for all the available directives.
