    Session Scope Variables


    Hi Experts,

    I want to create an object within the session scope
    (one that will be unique to everyone who logs into the system),
    yet persist throughout the login session.

    Would the "document" object suffice?
    ... or do I need to go up to the next level in scope?

      I 'm afraid that wouldn't help much. Javascript has no notion of sessions.
      It only knows the current page, it is born onload and dies onunload. You
      need some serverside technology like ASP or PHP to create sessions existing
      over multiple pages.

          Yes - this DOES help.

          Thank you very much.

          One question: What does the <server></server> tag pair do?

              Incorrect,
              inasmuch as "javascript " would mean "clientside d script".

              ASP understands serversided(!) J(ava)script
              and can use javascript accessable session variables and databases.

                  On Netscape (Sun ONE) Enterprise servers, the <server></server> tag pair
                  delimits server-side JavaScript code (or at least used to, I am not familiar
                  with their latest server offerings). Other application servers may use them as
                  well. Personally I'd recommend using a more robust server-side technology (such
                  as JSP or PHP), even when server-side JavaScript is provided.

                      This looks like good advice - thanks.

                          So I would use the <server> tags with ASP (as Grant Wagner pointed out).

                              No, not with ASP [on a Server running Windows]

                              Use:

                              <script language=jscrip t runat=server>
                              for (var i=0;i<10;i++) response.write( i+'<br>');
                              session("test") = ++i
                              </script>

                              Or:

                              <%@ Language=JScrip t %>

                              <%
                              for (var i=0;i<10;i++) response.write( i+'<br>');
                              session("test") = ++i
                              %>

                              Warning:
                              mixing(!) jscript and vbscript in ASP has it's peculiar priorities

                              For jscript and vbscript ASP questions I suggest the NG:
                              microsoft.publi c.inetserver.as p.general
