What is the disadvantage of AJAX?

1. It doesnot reloads the address bar of the browser. This is a disadvantage when a website uses friendly URLs.

2. It is not supported by the browser that doesnot have javascript enabled.

3. If the band width is low then Ajax performance will degrade Ex: check gmail when net is slow.

4. Also it is not SEO friendly.

5. Makes a barrier for Web crawlers and spiders
