is there any chance to show a loading bar while creating something in a loop with classic asp?

I thought about some ajax-style loading bar which shows that the page is stil creating something.

I tried to do it with session variables which contains status information of the process but on this i found out that asp servers have a queue which means you can run only one asp-page at the same time.

While loading the asp-page i cant open another asp-page on the sam server with the same session. With a new Session is this possible but i want to work with the same session ( if this is possible ).

Thoughts:
Can it be done with a ajax request which requests the asp-page and shows a loading bar while the page is loading?

Is there any workaround to work a status bar out?

(sorry for bad english)
Thank you

Edit:

I this way but i can’t access the session variable over a asp-page.
The session reader page gives me only a answer after the first asp-request is done. I think this is a session-queue-think.

it looks like this for me:

ajax page –(request process asp page)-> process.asp

(same ajax page) –(request session reader page)-> sessionreader.asp

while sessionstatus != 100 show process bar

the problem is i got a answer from sessionreader.asp when the process.asp is done. That is why i think this is a asp-session-queue-think.

Maybe it will work if a give the second request a new Session id (if this is possible at all) ?

    There used to be a trick with either disabling the Response.Buffer (set it to false) or let it be buffered, but from time to time you do Response.Flush as you want to update your progress.

    So, say you have your progress bar somewhere on top portion of your page (either image or table or div or whatever you want) and as you do something in asp script (say in a loop), from time to time, flush a javascript back to the client to update the progress bar that should already be on the screen. something like:

    <%
  REM Might be a good idea to set the timeout to some large number here...
  Response.Timeout = ...
%>
<html>
:
<body>
  <p>Please wait...<span id="progress">0</span>% completed.</p>
  : content here...
  <%
  REM Make sure the things above this get sent to the client first
  REM so they will be rendered before the rest of the page is rendered.
  Response.Flush()

  For iCnt = 0 To 100
    REM Do some stuffs here...

  %>
    <script>$("#progress").html(i)</script>
  <%
    Response.Flush()
  Next
  %>
  : some more contents here...
</body>
</html>

    I’m not sure if this still works with modern browsers, haven’t use it in a while.
