IIS 5 web applications initialization is not guaranteed

ground0(∵清爽∴清醒)
本文发表在 rolia.net 枫下论坛Hi there,

I have a weird problem with a web application in IIS 5 environment.

When an ASP is invoked from a browser, the web application should do
some server-side initialization work (calling Application_OnStart()
in global.asa).

But on this machine, this doesn't *ALWAYS* happen.
I write a pair of testing pages and install it as a seperate web
application in the same virtual web site. The same things happen again.

The testing pages source codes are as follows,

global.asa
==========
<SCRIPT LANGUAGE=VBScript RUNAT=Server>
Sub Application_OnStart
Application("testVar") = "abc"
End Sub
</SCRIPT>

test.asp
========
<%@ Language=VBScript %>
<html>
<body>
<p>Application("testVar")="<%=Application("testVar")%>"</p>
</body>
</html>

I invoked the page using http://localhost/testweb/test.asp
The screen displayed:
Application("testVar")="abc"
Then I unloaded the test application from IIS console and refresh the
screen, the value become empty (""):
Application("testVar")=""

I tried several unloadings and refreshings, some times it showed the
value, some times didn't.
I also changed the Application Protection between "Medium (Pooled)"
and "High (Isolated)", it didn't help either.

Please note that the same applications including the testing one work
fine on several single-cpu workstations (Windows 2000 Professional
and Windows 2000 Server with the same service pack level).

This machine's configuration is as follows,
Windows 2000 Server, build 2195, Service Pack 3;
Four way SMP, 2.5 GB memory;

Is there any special configuration on the server or any other software
installed there that could prevent the intialization?
