QUESTION ON SESSION VARIABLES

[Karen]

Hi there....
i got a quick one for you guys. i've this session variable that is
updated by calling a server method (i set this value when the user
hits a submit button in my form. The server method is called when i
load all my asp forms.). I'd like to be able to update this session
variable, without being forced to submit my form or refresh my form
(something that will call my server method each 2 min lets say,
without refreshing my page or submit)...is there anyway to do this???
Maybe a remote scripting with the setinterval() method?? but i'm
having trouble using this with XP and IE 6 !!

Your help is with this matter is higly appreciated!!

No. The only "something" that can update the session is the client. In the
simple world, anyway.

I neevr tried it tu update session variables (I have session variables with
passion) but calling an ASP page with an XMLHTTP call in JavaScript should
work (I never tried though).

Whoa! Typos!

I never tried to update session variables (I hate session variables with
passion) but calling an ASP page from the client using JavaScript and the
XMLHTTP object should work (I never tried it).

That's better, sorry about that!

on the client using setinterval:

var img=new Image("http://myserver/updatesession.asp?blah="+escape(new
Date()));

have updatesession.asp do the update to the session variable and then
redirect to a 1x1 gif or something.
The querystring part will force the browser to always make the request
instead of using the cache.

Karen,

If you want to run code on the server from the client, you must make a
request. One way to do this is to submit a form - which you *don't* want to
do - an another is to make a reqest by creating an image and setting its src
attribute to an asp page. This asp page has access to the user's session,
so it can update the session variable before returning the image to the
client.

################### client
<HTML>
<HEAD>
<TITLE> Session Update </TITLE>

<script>
var imgURL="http://myserver/updatesession.asp";
var iCount=0;
var tOut;

function doUpdate(){
iCount++;
var img=new Image();
img.src=imgURL+"?blah="+escape(new Date())
img=null;
document.getElementById("dMsg").innerHTML="Updated : "+iCount;
tOut=window.setTimeout("doUpdate()",2000);
}
</script>
</HEAD>

<BODY onload="doUpdate();">
<div id='dMsg'></div>
</BODY>
</HTML>

################ server (updatesession.asp)

<%

session("your_name")=session("your_name")+1
response.redirect "tiny.gif"

%>

OK?

Tim
