IBM HTTP Server Virtual Host: A Comprehensive Guide for Devs

Greetings Dev! In today’s digital world, websites play a crucial role in showcasing information and services to the world. A website with a unique domain name can host multiple web applications with different IP addresses. But what if you want to host multiple websites under a single IP? This is where IBM HTTP Server Virtual Host comes into play. In this article, we’ll discuss everything you need to know about IBM HTTP Server Virtual Host, from its basic concept to its advanced features.

What is IBM HTTP Server Virtual Host?

IBM HTTP Server is a web server program that delivers HTTP content to clients. Virtual host is a feature of IBM HTTP Server that allows hosting multiple websites under a single IP address. Simply put, virtual host enables you to specify which website should be served when a request comes in for a specific IP address.

Benefits of Using IBM HTTP Server Virtual Host

There are several benefits of using IBM HTTP Server Virtual Host, including:

How Does IBM HTTP Server Virtual Host Work?

When a client sends a request to a web server, it sends the request to the IP address associated with the website. The server then reads the incoming request and matches it with a specific virtual host. If the requested domain name matches the domain name of a virtual host, the server serves the content of that virtual host.

Creating Virtual Hosts in IBM HTTP Server

Here’s how to create virtual hosts in IBM HTTP Server:

1. Open the httpd.conf file located in the conf folder of your HTTP Server installation directory.
2. Locate the section and add the following code:

<VirtualHost *:80>
ServerName www.example.com
DocumentRoot /usr/local/apache/htdocs/example
</VirtualHost>

The above code specifies that any incoming request on port 80 with the domain name “www.example.com” should be directed to the folder “/usr/local/apache/htdocs/example.”

Advanced Features of IBM HTTP Server Virtual Host

IBM HTTP Server Virtual Host provides several advanced features, including:

• Dynamic Virtual Hosts: You can create virtual hosts dynamically using the RewriteRule directive.
• Name-based Virtual Hosts: You can create virtual hosts based on domain names.
• IP-based Virtual Hosts: You can create virtual hosts based on IP addresses.
• SSL Virtual Hosts: You can create virtual hosts that use SSL encryption.
