Each Web Agent requires its own web server instance. IIS web servers, for example, operate using a single instance on the computer on which is it installed. The number of IIS Web Agents equals the number of IIS web servers.
For other Web Servers that support multiple instances per computer, you can install and configure one Web Agent for each instance. For example, you could have one computer that runs three separate web server instances. Each instance has its own Web Agent. Therefore, one computer operates three Web Agents.

Creates child processes to handle additional requests.
Obtains additional threads from the connection pool to handle additional requests.
