I am trying to impliment the equivalent of SetTimeout to execute a function on a timed interval, server-side.<br><br>Specifically, rather than include code in individual loops, I would like to check every second or so to see if the client is still connected, something like (which doesn't work):<br><br>Function StillWorking()<br><br> if working=1 then<br> if response.isclientconnected=false then<br> response.end<br> end if<br> intTimerId = SetTimeout("StillWorking", 1000)<br> end if<br><br>end function<br><br>By the way, note "response.end" (works) which causes the script to end (more reliable way, I think, than using EXIT DO or EXIT FOR if you want to stop the script immediately).<br><br>Is there any way to do a "timer event" in server-side VbScript?<br>

Equvalent of SetTimeout for server-side?

Dear nazzaro,<br><br>HTTP is a stateless non-persistent connection oriented protocol. Even though version 1.1 allows for keeping the connection open it is designed for use by the browser only so that it doesn't have to create a new connection for every file(resource) on a page. This optimizes total page download time.<br><br>You can make your code 'sleep' if you want before sending more response data to the browser but it is all part of the single request/response pair that initiated the instance of your code.<br><br>Using a 'push' design is the only way to truly perform server side initiated client updates.<br><br>Hope this helps<br>-pete

Sorry, but I apparently, didn't explain the application well enough.<br><br>The application queries a database, does lot's of data manipulation and sends a table to the client.<br><br>The "timer" that I want to use has nothing to do with the client. I need it to interrupt the server processing of the script periodically BEFORE the table gets sent to the client.<br><br>Would it be possible to use "Timer1 = Server.CreateObject ("blah1.blah2"
" to make a timer control available to asp?<br><br>If so, what would the "blah1" and "blah2" be (to use the regular VB timer control, which should be on the server I'm currently using since VB6 is installed there)?

I mean you can't create a new thread from your script to watch and interrupt the main thread of your script.<br><br>-pete
