Help, the simplest code doesn't work well, but where is the problem?

Hi:

When I tried the following code, I got an error:

if I clicked "Click me" button more than one time, and than click "back"
button in the IE browser Toolbar, I will get an error: "The page cannot be
displayed......".

But I won't get any error if I only click the "click me" button one time and
then click the browser's "Back" button.

In fact, this is an example from the Book "Essential ASP.NET with Examples
in C#" by Fritz Onion ( Listing 2-5). Please try this simplest code and tell
me if you get the same problem. What causes the problem? Maybe it is caused
by webserver setting?

Can anyone help me!

The page is set to time out most likely. You should not be able to use the
back button on a form. There are nicer ways of telling the user, however.
Have not seen this particular book.

Hi:

Thank you!

I tried the same code in another machine, it works! No matter how many the
click times are, I can click "Back" button of the browser without getting
any error. So I think it should be a configuration issue.

And I checked the web.config file and the value of "timeout" in
<sessionState> is "20".

Where is the problem? Where can I check?

It looks more like a client side issue as you have a different effect on two
machines. Check perhaps the "cache settings" in IE.
