and another discovery:
if the session is null, Session.IsNewSession is true .... with the same
SessionID like before...
Newsbeitrag i'm not using frames in my test-environment ...
How du I use System.Web.ProcessModelInfo.GetHistory ?
BTW the applicationstate and the sessionstate variables are disappearing
independet of each other.
Output also the current date and time as well as the session id (to make
sure there is no cache issue and to see if the session is the same or
not).
You could as well try Session.IsNew (if I remember) to see if it's
considered as a new session (despite perhaps using the same id as you
mentionned)..
Though you mentionned that the aplication doesn't restart could you
double
check this (for example using the performance counter or by using
programmatically System.Web.ProcessModelInfo.GetHistory)... If the
application restarts it could perhaps loose the session variable
while
keeping the same session id...
BTW do you still use frames ? Does it happens without frames ?
Good luck.

message de it has all its order... in my "test-environment" i call the pages
sepereately. at first the sessiontest1.aspx and after it the
sessiontest2.aspx
And how are these pages related ? Are they both used in the frameset
?
In particular if they are both used in the same frameset I'm not sure
the
order in which they are called is predictable.
I would do something like :
- in both pages add something to the current value of the testvar
variable
(such as a datetime and the name of the page) and display the
value
- this way when printed you'll see in whic order it was loaded
You could also simply try to see in the IIS log if one is always
called
before the other or if it's sometimes the other way round...

"Alexander Widera" <

le
message de ok... all details.... i tried some other simple code .. and the same
problem
sessiontest1.aspx:
<%@ Page Language="C#" ContentType="text/html"
ResponseEncoding="iso-8859-1"
Trace="true" %>
<script runat="server">
public void Page_Load(Object sender, EventArgs e)
{
Session.Add("testvar", "123");
if (Application["timestamp"]==null) Application.Add("timestamp",
DateTime.Now);
}
</script>
No error on call.... .... it creates a sessionvar named "testvar"
and
sets
the value to "123" ... the script also sets an applicationvar
"timestamp"
to
the current time.
sessiontest2.aspx
<%@ Page Language="C#" ContentType="text/html"
ResponseEncoding="iso-8859-1"
Trace="true" %>
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
Response.Write("tv: " + Session["testvar"] + " and TS:
"+Application["timestamp"]);
}
</script>
A simple output .... but sometimes the sessionvar is null.. .and
sometimes
it is "123"...
After many tries I also found out, that it's the same with the
applicationvar .... both "disappear" at the same time ....
I have a trace for you....
at first the trace with both vars working:
