    Security with AJAX is of course an important consideration as it's asychronous and a malicious user could write data back to your database if implemented incorrectly.

    That statement is a little misleading, as security is not directly related to requests being asynchronous. I think what the poster meant is that being asynchronous, AJAX application make lots of calls to the back end. In a non-AJAX app, typically you fetch the data during the page load. In AJAX app, users request sections of the page to be refreshed, meaning a lot more finely grained methods to the backend are exposed.

    non-AJAX:
        LoadMainPage()
    AJAX:
        LoadTitles()
        LoadSections()
        LoadSummary()

  2. "AJAX" alternative? by greywire · · Score: 2, Interesting

    Can somebody please come up with a name other than AJAX? I find myself talking about the programming techniques covered by the moniker of "AJAX" (herein after refered to as "BLURG") and wanting to call it something other than "AJAX":

    BLURG is not necessarily asynchronous: you may be updating only a small part of the page, but doing it synchronously.

    BLURG does not require XML. In fact you could be returning HTML, Javascript, CSV, JSON, etc.

    BLURG does not even require the XmlHttpRequest feature and BLURG techniques have been in use far before the existance of this feature.

    Can we please come up with a better name for BLURG, one that covers the more general programing techniques involved? Something for us people to use that is NOT just the trendy new thing known as AJAX? Something that we can use that will let others like us know that we have been aware of these techniques even before the term AJAX was coined?

    For now I will call it BLURG...

      I've read and believe that AJAX is being or has been de-acronym-ified...

      AJAX is just a proper noun now, referring more to the user interaction style used in the BLURG apps you mention, and doesn't need to use any specific technology.

      i.e. Don't shove the whole user interface down the pipe every time the user clicks... adapt the interface as work progresses... etc.

      The term is probably here to stay... so we might as well make it mean what we want it to.
