AJAX and Web Services

Widely used applications, such as Google Maps, Google Suggest, Amazon, and Gmail, are all built using AJAX (asynchronous JavaScript and XML). Learn the concepts necessary to build AJAX applications, and discover how AJAX can help developers create dynamic web application experiences while eliminating deployment problems and lackluster user experiences. Using AJAX, developers facilitate asynchronous requests to the web server while the client continues to interact with the webpage. Become familiar with the HTTP request and response paradigm, and learn how to manipulate and take advantage of HTTP headers such as caching, redirects, and virtual hosting. Work with different techniques for parsing JSON and XML data streams using DOM (document object model) navigation. Study JSONP, and learn how to use JavaScript script tags to bypass AJAX restrictions on “same-domain policy.” Create web services and deliver them to clients for webpage interactive processing.
