Apparently this is an old idea with the new buzzword Comet.... (http://ajaxian.com/archives/comet-a-new-approach-to-ajax-applications)
Since web servers cannot just push updates/data to client browsers with HTML, the poor client must often keep *polling* the server in web land. This isn't scalable for obvious reasons. A clever solution is to replace polling with a single query that keeps sending whitespace to keep it alive. Rather than building and tearing down HTTP connections to server all the time (with polling), we can just work around the browser's timeout values by keeping one connection alive until server has data for it!!! This seems to solve a lot of problems of HTML and have lots of potential for future dynamic AJAXy type web apps.
