AJAX- the acronym for Java Script and XML brings a dynamic group of interrelated programming and web development technique to create asynchronous web applications for different clients. The AJAX technology is basically meant for increasing the web page's interactivity, speed, and usability. The expert developers who are proficient in Javascript, HTML, CSS and XML can start efficiently and speedily on AJAX Technology and the client should consider such experts only.

AJAX helps the developers to use a great conglomeration of already existing technologies altogether in a more definite and advanced form. This would certainly include HTML or XHTML, Cascading Style Sheets, JavaScript, the Document Object Model, XML, XSLT, and the XMLHttpRequest object. When these technologies are combined in the Ajax model, web applications are able to make quick, incremental updates to the user interface without reloading the entire browser page.

By using the latest AJAX Technology, Infoicon Technologies brings the most effectual website development strategies by implementing the latest AJAX Technology to make a successful website. Some of the most panoptic features and usages of the latest AJAX Technology can be inculcated with Infoicon Development services are:

AJAX Browser Support

As this is the most featured and latest technique of developing sites in a more dynamic form; and interestingly, but not problematically all the available browsers cannot support AJAX. So please check the list of the browsers that support this technology for avoiding any annoyance in working:

  • Mozilla Firefox 1.0 and above
  • Apple Safari 1.2 and above.
  • Konqueror
  • Netscape version 7.1 and above
  • Microsoft Internet Explorer 5 and above
  • Opera 7.6 and above

AJAX in Action

When the AJAX Technology is in action, we the Infoicon professionals take the following steps for productive results:

  • A client event occurs
  • An XMLHttpRequest object is created
  • The XMLHttpRequest object is then configured
  • It further makes an asynchronous request to the Webserver.
  • '
  • Webserver returns the result containing XML document.
  • The XMLHttpRequest then object calls the callback () function and processes the result; and finally
  • The HTML DOM is updated

AJAX XMLHttpRequest

Key to AJAX the XMLHttpRequest object has been available ever since Internet Explorer 5.5 was released in July 2000, but not fully discovered before people started to talk about AJAX and Web 2.0 in 2005. XHR is an API that can be used by JavaScript, JScript, VBScript and other web browser scripting languages to transfer and manipulate XML data to and from a web server using HTTP, establishing an independent connection channel between a web page's Client-Side and Server-Side.

The data returned from XMLHttpRequest calls will often be provided by back-end databases. Besides XML, XMLHttpRequest can be used to fetch data in other formats, e.g. JSON or even plain text.

AJAX Security Applications

AJAX-based Web applications will bring different security schemes of regular Web applications for authentication, authorization, and data protection requirements in web.xml file (declarative) or in your program. They are subjected to same kinds of security threats as regular web applications. The Java Script code is visible to a user/hacker which can be misused for inferring server side weaknesses. JavaScript code can be downloaded from the server and executed ("eval") at the client and can compromise the client by mal-intended code
