Hi All


I am working on a project that basicaly had Call Detail Records streamed to a database at the moment I am updating the info to the browser every 30 minutes but intend on streaming the data real time from the db to the browser so the reports are concurrent with the real time data sent to the db. I am not sure wether or not to use non parsed header scripts or Meta tag refresh please can some one advise on how to do this .

Kind Regards

Ross

Are you not using the meta tag at the moment?

Check out this site: http://www.geosense.net

It's a pretty neat little game, and last time I checked it sent and retrieved data from the browser with javascript without reloading the page. It's a working example, so perhaps it'll be of use.

Btw, I don't think you can "force" realtime data to the browser. The browser has to initiate the exchange. But, maybe there's a way.

You could use Javascript to keep checking the server once every few seconds or so. Generate an XML doc on the server with the data in it and use the MSXHTML ActiveX control to retreive it, and display the data how you want. Maybe use an XSLT document that's already downloaded with the first page view to do it. You may also want a very small XML doc that simply contains weather or not the data has changed, thus conserving bandwidth if there's a lot of data that might not change that often.
