      Hi,

      I am trying to refresh a datatable on a timed basis. However, each
      time I do the sendRequest, the same data is always returned. In
      fact, if the web server is stopped, I still get back the same data
      after the first request. It seems like the DataSource object is
      caching the first set of data but I can't figure out how to turn
      caching off. The documentation says that caching is turned off by
      default so I am confused. Any help would be appreciated. BTW, I am a
      new javascript programmer but have experience in other languages.
      Below is the code :

      Thanks in advance
      Gary

        IIF you are using Internet Explorer, there is a stupid default
        settings under Tools -> Internet Options -> Browsing History ->
        Settings that needs to be changed. By default, "Check for new
        versions of pages" is set to "Automatic" (whatever that means).
        Change it to "Every visit to the page". Even dynamic pages (with
        query strings) are cached by IE. Absolutely ridiculous, but that's
        what it does by defalt.

        This won't be the problem in other browsers though.

          The problem is with caching. You can tell IE not to cache, which will
          prevent it from caching everything from your site or others or you can send
          the proper headers from the server side to tell the browser the page is
          expired. In PHP you can do:

          header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1
          header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past

          right before echoing any content. Those headers tell the browser (and any
          intermediate caching proxy) that the page is not to be cached and, just in
          case, that it has already expired.

          I am having the same problem with a datatable that is similar to the Local XML example (http://developer.yahoo.com/yui/examples/datatable/dt_xhrlocalxml.html).

            I am having the same problem with a datatable that is similar to the
            Local XML example
            (http://developer.yahoo.com/yui/examples/datatable/dt_xhrlocalxml.html).
            It reads my xml file from cache unless I specifically clear the cache
            between reloads. I'm not using PHP. Where/How would I set these
            headers in this case?

                I copied the local XML example from the examples page and plugged in
                my own xml file to read/write to/from. I'm using CGI to do the adds
                and deletes from the local xml file. I'm using Connection to read in
                the data. This GET reads from the cache whenever it can which is not
                what I want it to do.

                this.getXML = YAHOO.util.Connect.asyncRequest("GET", "data.xml",
                this.connectionCallback);

                  Unfortunately, I don't know how you can do it in your setup. A trick I know
                  you can do from the client side is to add a fake argument to the URL and
                  make that argument a random number. In this way, no matter what any
                  intermediary has cached, since the URL is different every time, it will
                  never be reused. The problem is that it is a wasteful solution, since
                  whatever is caching the pages will still cache them, though they will never
                  be used again, wasting time and spending resources that could be better used
                  caching good pages.

                  The best solution is for the source of the information, the server, to
                  indicate all parties that the information should not be cached at all, thus,
                  wasting no time or other resources. Some servers have a 'raw' file format
                  so that the server will transmit the page as is, with all the headers as
                  they are in that file. Others allow you to set a configuration file on the
                  directory that can carry such information as cache control.

                    Thanks. I'm looking into apache config settings. I actually tried the
                    work around you suggested at one point. It was fine until I opened my
                    cache and had hundreds or perhaps thousands of versions of the file
                    around.
