How to Make your site Internet Explorer 8 Compatible – Part 5 – Better AJAX API

Internet Explorer 8 provides an simplidied programming model for AJAX development that spans browser, webpage, and server interaction.
Web developer can easilly build more functional webpages with better end-user experiences as well as performance.

Some of the AJAX Improvements in IE8 are explained below:

1. AJAX Navigation: This enables end-users to navigate back and forth without leaving the AJAX application and without performing a traditional full navigation.
2. DOM Storage: This is a simple-to-use method for storing and retrieving strings of key/value pair data in cache. This provides faster access and reduces the effect of network latencies.
3. Connectivity events allow websites to check when the user is connected to the network and receive notification of connectivity changes.
4. Six connections per host instead of two, which allows parallel downloads and in turn improved performance.
5. Cross-domain communication is an integral part of AJAX development and mashup Web applications. In IE8 Cross-domain Request(XDR) and Cross-document Messaging(XDM) API’s are provided for this purpose only.

In short, all these improves the AJAX Usage for developers as well as for end-users to move towards a better web experience with AJAX.
