• Back functionality cannot work because the dynamic pages don’t register themselves to the browsers history engine. Hence the need of Iframe becomes essential.
• The page cannot be bookmarked if implemented using Ajax.
• If java script is disabled , Ajax will not work
• Because different components of the pages are loaded at different times, response time may be slow.
• Because different components of the pages are loaded at different times it may create confusion for the user.
