And if the user clones the window as the originator of this thread
postulated, will that name property still contain our identifier? No.
It would probably help the cause of enlightenment if you remembered the
original question instead of inventing your own.
...
<script type="text/javascript">
// you must obey the rules for window names, set by DOM Level 0, here
if (typeof window.name != "undefined")
{
if (!/^_myWindow/.test(window.name))
{
window.name = "_mywindow" + new Date().getTime();
}
}
</script>
...
</head>
This will assign the Window object a new unique name when the corresponding
window is opened (or "cloned"), and will keep that value if it is
refreshed, or navigation happens in it. And the best part of it is that it
works with tabs, too.[1]
Let me again state the requirements:
1. If I navigate pages in the same browser window, the session (aka
"window identity") stays the same. Ditto for navidating with browser
"go back/forward one page".
2. If window is cloned, the identity should change. Ditto for browser
tabs.

Nice try. Doesn't work.
JSP page code:
[...]
<form method="post" action="">
<input type="button" name="b001" value="Button"
onClick="alert(window.name);submit()">
</form>
[...]
The name of the window keeps changing whenever I press the button.

"window identity") stays the same. Ditto for navidating with browser
"go back/forward one page".
2. If window is cloned, the identity should change. Ditto for browser

BTW, CTRL-N doesn't clone window in Mozilla (it invokes new windoe with
the default page). Am I missing some setting?
What is the session definition? Session is some linear
sequence of pages that user can navigate back in forth in time. Any
time a web page gets cloned into a new tab or browser window, a new
session is spawned. This is a new session because the old one is still
present and there is no way to merge the new session into the old one.
VK said:That is the most odd session definition I've ever seen so far (and I
saw a lot of odd things). Session (from the server point of view) is
the moment of the first request for a transaction and till the moment
of the final request finishing the transaction. If it's a multi-step
transaction, on the first request your create an unique session ID and
a session record/file to keep the intermediate submission data. On each
new request you check these data and if the session is not expired and
credentials (if any) are in order you serve the next step page. You
cannot control how did the current request came to you: from the
original browser window, or user cloned it in 25 copies and submitting
from from each of them, or refreshing the window, or she reverse
engineered your form and using XMLHttpRequest with timed loop. These
are just very tops of things a "curious" user may do. If you are really
so concerned about transactions stability, then the matter is way above
of JavaScript domain and any "window identification" cheat-chat. You
need first to program the decisions server-side:
1) how long the session is kept before marked expired.
2) if transaction record stopped on step 5 and next request came for
step 2, are you serving step 2 with roll-back data or will you say
"sorry Joe, no way"
3)
4)
5)

Some good book about transaction server could be really helpful here.
support) with C-N, or the window or tab with Tabbrowser Extensions in
Firefox/1.5.0.2, in Opera/9 Beta, and in Konqueror/3.52, the window
name definitely changes.[1] With the above correction, it does not
if I refreshed the document or navigated in that window afterwards,
including submit to the same document resource.
