What is the difference between AJAH and AJAX?

While reading about ASP.NET Ajax toolkit I stumbled upon the term AJAH. What 开发者_开发百科is it and how is it different from Ajax?

AJAH is someone's attempt to come up with a new buzzword to mean "Having JavaScript make an HTTP request and get back a blob of HTML instead of a blob of XML".

Since Ajax has been taken to mean "Having JavaScript make an HTTP request and get back anything at all" (most often JSON these days, but a blob of HTML is also very common), it is a pretty pointless attempt.

Quote taken from here.

With true AJAX, a call is made to the server, the nicely formatted data is returned and the client application extracts the data from the xml, and replaces whatever elements need to be replaced on a page. With AJAH, a glob of html is returned and slapped into the page.

So basically, AJAH returns pure HTML, AJAX returns formatted data, such as JSON that is dealt with with by the client scripts.

Personally, I think this just looks like a term only a few developers have used. It's definitely not mainstream.
