Asynchronous Support in Web Protocol

Asynchronous support in Web Transport supports testing of asynchronous behavior in web applications.

The following asynchronous behaviors are supported:

The terms used in asychronous-related topics are:

Asynchronous ConversationAn Asynchronous Conversation is a series of related web tasks, including tasks caused by redirection. An Asynchronous Conversation starts with the request for the desired response, includes all the requests and responses that are caused by this request (authentication, redirection, and so on) and ends when the desired response is received or when the series of interactions is canceled.

Asynchronous Conversation PatternA Pattern consists of one or more web tasks, issued and responded-to according to a predefined pattern, such as push, poll, or long poll. A Repetitive Pattern consists of more than one Conversation. For example, polling.

TaskA web task consists of an HTTP request and any directly related HTTP responses and requests until the eventual HTTP response to the initial HTTP request. Redirections are not included in an RDR.
