Session Variables

[Jim Heavey]

How would I iterate over the session varriables listing all the names of
the session variables which currently exist?

Why would it be that if I set a session variable and then immediately
redirect to another page, why would the session varriable not be in
existence?

Thanks in advance for your assistance!!!!!!!

Session variables are stored immediately I believe so you
must be losing your session from page to page. Check if
you have declared enableSessionState=true in the
<@Page ...> directive on all pages that use the session.
You can also paste something like this into your
web.config to enable session for all pages:
<pages
enableSessionState="true"
/>

Jim, session time-outs will cause session object to loose
their values. Here is a very simple example of creating a
session object, redirecting to another page and then
reading the session object value:

Page 1
======

Page.Session("NewAccount") = "True"
Page.Response.Redirect("summaryPage.aspx", True)

Page 2
======

If (Page.Session("NewAccount") = "True") Then

End If

I hope this helps.

Hi,

For your first questio, to list your session variables, the following
should work

Dim i As Integer

For i=1 To Session.Count
Response.Write(Session.Keys(i) & " = " & Session.Item(i) & "<br>")
Next

For your second question, session variables not being retained from
one page to the next.

Do you use ZoneAlarm Pro? If so, you need to enable third party
cookies for your local site. IIS uses a cookie to propogate the
SessionID from page to page, and it may be that ZoneAlarm is dropping
this cookie, so when IIS gets to the next page it thinks it's a new
session. (I had this problem myself, which took about a week before I
found the answer (on this newsgroup, I think)).

Marc.

Oops.

That For loop should have been

For i=0 To Session.Count - 1

but I'm sure you spotted that.
