(October 7, 2005) - AJAX isn't a technology, or a language, and there's no
recipe to implement it; it's just a combination of various components to
achieve something you otherwise couldn't: asynchronous http requests.
However, since early 2005, when Google and Flickr popularized the concept,
its use has grown rapidly.
The name AJAX is short for Asynchronous JavaScript and XML. It uses the
JavaScript XMLHttpRequest function to create a tunnel from the client's
browser to the server and transmit information back and forth without having
to refresh the page. The data travels in XML format because it transmits
complex data types over clear text.
AJAX uses XHTML for the data presentation of the view layer, DOM, short for
Document Object Model, which dynamically manipulates the presentation, XML
for data exchange, and XMLHttpRequest as the exchange engine that ties

Should you use the old iFrame tricks or the new XMLHttpRequest? There is not
better or worse when comparing these two techniques, but they are certainly
different. While both of them allow you to communicate with the server in the
background, you should choose the appropriate for your situation depending on
a few questions: Do you want the back-forward buttons to work? Do you plan to
perform more than one simultaneous request? Do you need cross-site calls? Do
you need to monitor the status of your calls?
I'm pretty sure there are more differences, and way around the ones I will

It's become very popular lately, even though it's not exactly new. It's been
possible to use the concept behind AJAX since browsers introduced the
XMLHttpRequest function in 1999.

ajaxCFC update for DRWUtil.AddRowsRelated Categories: ajax, ajaxCFC,
Coldfusion, JS/DHTML A recent message in the ajaxCFC group asked about the
DRWUtil.addRows() function; the truth is that I had never used it. I include
the utils library because there are other elements that I find useful, but I
had never given the addRows a try.
Enough said, since I include the file, I guess I need to support the built-in
functionality, but the addRows out-of-the-box was accepting arrays and
objects. I serialize the ColdFusion queries into a more complex object which
was not recognized by the a... (more)
Will web applications ever replace regular desktop applications? Will desktop
applications adopt web paradigms? Are web applications "Web 2.0"?
The whole 2.0 thing is getting much abuse now; its hype/meaning ratio is
inflating by the minute. Web 2.0 is really exposing functionality through
APIs and allowing people to collaborate, much more than it is about Rich
Internet Applications.
The first impression when you ask anyone about Web applications is negative;
they claim they will never use them. I certainly cannot see (yet) a Photoshop
or Avid web application, but let's go back a... (more)
