Managed channel for asynchronous requests

A method configured for use with a data processing system, wherein the data processing system comprises a client and a server, the method comprising:

• receiving a call from a client web application to a first method of a native XmlHttpRequest (XHR) object, wherein the first method comprises a first Asynchronous JavaScript +Extensible Markup Language (Ajax) request to the server, and wherein the first Ajax request comprises a first plurality of attributes;
• wrapping the native XHR object to provide a wrapped call to a second method of the wrapped XHR object, wherein the second method comprises a second Ajax request to the server;
• converting the wrapped call into a message, wherein the message comprises the first plurality of attributes;
• intercepting the received call from the client web application to the first method of the native XHR object;
• calling the wrapped call to the second method of the wrapped XHR object instead of calling the first method of the native XHR object, wherein the second method is different from the first method;
• setting a unique message identification code for the message;
• sending the message on a channel configured to transport a plurality of asynchronous messages over a network from the client to the server;
• receiving the message on the channel from the client;
• decoding the received message to provide a request, wherein the request comprises the first plurality of attributes;
• in response to providing the request for fetching a response, sending the request to a resource;
• and
• setting a reply unique message identification code to a reply corresponding to the unique message identification code of the message to correlate which reply corresponds to which message of the plurality of asynchronous messages transported on the channel.

• wrapping the native XHR object to provide a wrapped call to a second method of the wrapped XHR object, wherein the second method comprises a second Ajax request to the server;
• converting the wrapped call into a message, wherein the message comprises the first plurality of attributes;
• establishing a channel to the server configured to transport a plurality of asynchronous messages;
• intercepting the received call from the client web application to the first method of the native XHR object;
• calling the wrapped call to the second method of the wrapped XHR object instead of calling the first method of the native XHR object, wherein the second method is different from the first method;
• setting a unique message identification code for the message;
• sending the message on the channel;
• and
• correlating a reply unique message identification code set by the server to a reply corresponding to the unique message identification code for the message to identify which reply corresponds to which message of the plurality of messages sent over the channel.
