asp_components thread: Simultaneous access of ASP Files behaves abnormally

Hi
I have the following code block. Now here i have a delaying mechanism thru
For-loops which take the upper limit of the loop from a QueryString
Parameter "Wait".
Now i tested the url with two IE windows open. The urls and sequence of
calling is as follows
window 1 - http://pr-domain/satish/list_authors.asp?Wait=5000
window 2 - http://pr-domain/satish/list_authors.asp?Wait=0
I expect the result to be displayed in window 2 much before the result is
displayed in window 1.
But the result in window 2 is displayed only after window 1 is rendered.
The code is being run on W2K machine.
The result is same on W98 with PWS
I am perplexed. Please help me

The following is the code block
<%
set objXML = Server.CreateObject("Microsoft.xmlDOM")
objXML.loadXML("<test><student studentid=""1""

why are you attempting to make one page wait?

The web server doesn't really run the pages "Simultaneously". So when you
have one page that ties up the processor for some time, that's it. If the
second page request is sent after the first, but the first is still working,
then the second request will just sit there like you are seeing until the
first is done processing.
Why are you trying to do this?
