What are the disadvantages of AJAX?

 Posted by Ddd on 3/23/2011 | Category: ASP.NET AJAX Interview questions | Views: 5174 | Points: 40

These are the disadvantages:

1) AJAX is dependent on Javascript. If there is some Javascript problem with the browser or in the OS,your AJAX functionality may not work.
2) Search engines generally do not index Javascript present in web pages. AJAX can be problematic in Search engines as it uses Javascript for most of its parts.
3) source code written for AJAX is easily human readable.
4) Debugging is difficult. We have often to use additional Javascript code for that.
5) Data of all requests is URL-encoded. It increases the size of the request. It can cause problem while Paginating through GridView if there is a huge data.
6)Slow and unreliable network connection.
7)Problem with browser back button when using AJAX enabled pages.
