Web Application Communication Overview

The topics in this section offer an overview of synchronous and asynchronous Web application processing flow, including the three main asynchronous communication models. They also examine the implications of AJAX on automated load testing and the use of XPATH in identifying DOM elements.

  1. Understanding Synchronous and Asynchronous Communication
    Explains that in traditional Web-based applications, a user input triggers a number of resource requests. Once the requests have been answered by the server, no further communication takes place until the user's next input.
  2. Asynchronous Communication Models
    Explains that there are three main types of asynchronous request and response sequences: push, poll, and long-poll.
  3. Testing Asynchronous Communication on the Protocol Level
    Explains testing of web applications that use asynchronous communication patterns such as polling, long-polling, and push.
  4. Testing WebSocket Connections
    The WebSocket protocol allows to establish a full-duplex (bidirectional) connection between client and server. This topic explains how to record WebSocket communication and how to script WebSocket BDL functions.
  5. HTTP/2 Support
    Describes what HTTP/2 is, its main characteristics and current limitations, as well as how Silk Performer supports HTTP/2.
  6. Testing AJAX Applications
    Explains that AJAX is a group of interrelated Web development techniques that are used on the client-side (browser) to create interactive Web applications.
