AHAH = Asynchronous HTML and HTTP is a subset of AJAX without the X(XML)

• Update web pages dynamically using JavaScript and XHTML, instead of XML.
• Like in AJAX, use XMLHTTP to raise a Request.
• The state-change of the request when the Response is received is directly passed on to a Function.
• The response is directly fed into the intended target element (Div) of the document using the innerHTML attribute of elements.
• Unlike AJAX, the response is not parsed at the client side.
• Technically, its a subset of AJAX without the X (XML)
• Works when you dont change the content structure of the XMLHTTP response.
• Doesn’t work when you call HTML files with external .css and .js files.
• Code is very simple (about 20 lines)
• Was first used couple of years ago.
