Re: [WebDNA] HTTP Streaming -- impossible?

This WebDNA talk-list message is from

texte = > I just ran a test, and entering all asterisks in the timer fields, including the "Second" field, results in a trigger that executes every second. Give it a try. Thanks for the test Brian, I should have thought of that. The instructions are wrong in this case, but at least it makes my trigger management easier ... :) > If you had a trigger that ran once per second and wrote the auction status to a text or xml file, you could use XMLHttpRequest (AJAX) to fetch that file from the client page and update the page content with the results. This would execute very fast, and not bother WebDNA with every client request, just with the once-per-second trigger. I was working on this approach a year ago or so on another website, but the project ended prematurely so I never learned how this works, and that's why I'm going to ask: How does the XMLHTTPRequest know when the file has changed on the server? It needs to know this so it can download the new and updated file, right? Sincerely, Kenneth Grome Associated Messages, from the most recent to the oldest:
