Chapter 1 Web Technologies Overview 15

SSL Support

Web service includes support for Secure Sockets Layer (SSL), a protocol that encrypts

information being transferred between the client and server. SSL works in conjunction

with a digital certificate that provides a certified identity for the server by establishing a

secure, encrypted exchange of information.

Dynamic Content With Server Side Includes (SSI)

Server side includes provide a method for using the same content on multiple pages in

a site. They also can tell the server to run a script or insert specific data into a page. This

feature makes updating content much easier, because you revise information in only

one place and the SSI command displays that revised information on many pages.

See “Enabling Server Side Includes (SSI)” on page 49 for more information about SSI.

Front-End Cache

The web server includes a high-performance cache that increases performance for

websites that serve static pages. The static content stays in the cache once used, so the

server can quickly retrieve this content when it is requested again.

See “Improving Performance of Static Websites (Performance Cache)” on page 37 for

more about using the performance cache.

Weblogs and RSS Support

The web server provides weblogs (blogs) as an option for each website. The weblogs

comply with RSS and Atom XML standards and allow Open Directory authentication.

Log users can choose from several techniques for working with templates and style

sheets. Weblogs in Mac OS X Server are based on Blojsom, an open source application.

Note: When you turn on weblogs, they are on for every site on the server.

Detailed coverage of weblogs is provided in Chapter 3, “Weblog Service,” of the

collaboration services administration guide.

Before You Begin

This section provides information you need to know before you set up your web server

for the first time. You should read this section even if you are an experienced web

administrator, as some features and behaviors may be different from what you expect.

Configuring Your Web Server

You can use Server Admin to set up and configure most features of your web server. If

you are an experienced Apache administrator and need to work with features of the

Apache web server that aren’t included in Server Admin, you can modify the

appropriate configuration files. However, Apple does not provide technical support for

modifying Apache configuration files. If you choose to modify a file, be sure to make a

backup copy first. Then you can revert to the copy should you have problems.
