HTTP Adaptors

This chapter provides detailed information about the HTTP adaptors that are included in a WebObjects Deployment installation. The HTTP adaptor is an important piece of an application site. It sits between your web server and your application instances. It forwards requests from the web server to the appropriate application instance and responses from the instance back to the web server. It also performs load balancing between instances of an application.

This chapter contains the following sections:

• “Adaptors, Applications, and Hosts” provides a high-level view of the interaction between the HTTP adaptor, application instances, and application hosts.

• “Types of Adaptors” explains the differences among the two types of HTTP adaptors that you can use on your site.

• “State Discovery” describes how to configure an HTTP adaptor to obtain your site’s state dynamically or using a configuration file. It also explains how to change a dynamic configuration into a static one.

• “The WebObjects Adaptor Information Page” shows an example of the web browser page that displays information about an HTTP adaptor.

• “Customizing HTTP Adaptors” summarizes all the settings available for HTTP adaptors.
