In the following figure, customer A uses www.a.com as their domain name, and customer B uses www.b.com. Company C has a limited number of public IP addresses and wants to assign them conservatively. They implement virtual hosting, advertising a single virtual server IP address that includes Web sites for both company A and company B. Additionally, the hosting company assigns only one service (HTTP port 80) to support the virtual server.
The virtual hosting company wants to place different types of content on different servers. To efficiently use their servers, they separate them into two groups--their fastest servers process dynamic content (such as .cgi files) and their slower servers process static content (such as .jpg files).
In the above figure, the hosting company groups all the real servers into one real server group even though different servers provide services for different customers and different types of content.
1
A
Static .jpg files
2
A
Static .jpg files
3
A
Dynamic .cgi files
4
B
Static .jpg files
5
B
Dynamic .cgi files
When the virtual hosting company receives a client request with www.a.com in the Host Header and .jpg in the URL, it is load balanced between server 1 and server 2. For this configuration, you must assign multiple strings (a Host Header string and a URL string) for each real server.
