Configuring the HTTP Service

The HTTP service is the component of the Enterprise Server that provides facilities for deploying web applications and for making deployed web applications accessible by HTTP clients. These facilities are provided by means of two kinds of related objects, virtual servers and HTTP listeners.

This chapter discusses the following topics:

Virtual Servers

A virtual server, sometimes called a virtual host, is an object that allows the same physical server to host multiple Internet domain names. All virtual servers hosted on the same physical server share the Internet Protocol (IP) address of that physical server. A virtual server associates a domain name for a server (such as www.aaa.com) with the particular server on which the Enterprise Server is running.

Note – Do not confuse an Internet domain with the administrative domain of the Enterprise Server.

For instance, assume you want to host these domains on your physical server:

www.aaa.com

www.bbb.com

www.ccc.com

Assume also that www.aaa.com, www.bbb.com, and www.ccc.com have web modules web1, web2, and web3, respectively, associated with them.

This means that all of these URLs are handled by your physical server:
