asp_web_howto thread: Session TimeOut ...

Message #1 by "Melissa Mussitsch" <melissa.mussitsch@a...> on Thu, 30 May 2002 14:35:51
I am not using a Session Object with ASP, but just the Connection Timeout 
period set on the Web Site.  I wanted to know if there was a way to trap 
for the timeout so that I can display something friendlier than the 
typical "You are not authorized to view this page" page that gets 
displayed.

Any ideas?
Thanks.

Hi Mellisa !

I didn't find anyway to do it :(.

What I am doing is set some function to be executed when this timeout
time passed. The tricky thing here is that this function must to be reset
every time when new page are requested from the server since this timeout
start countdown from last page request.

Let me know if you find some better and simplest solution from mine
cause I know that its works so far but I defiantly would like
to improve it.

Oleg.

This is what we use to redirect users when their session times out.  It is
just a javascript, but it works and will reset everytime the page is
refreshed.

//Code for the session timer
        var mytime = 0;
        var mysecs = 0;
        var Errormsg = "Your session has timed out."

        function sessionTimer() {
                mysecs++
                if (mysecs == 60) {
                        mytime++;
                        mysecs = 0;
                }
                setTimeout("sessionTimer()", 1000);
                if (mysecs < 10) {
                        defaultStatus = "Session Time: " + mytime + ":0" +
mysecs;
                        window.Status += "Session Time: " + mytime + ":0" +
mysecs;
                }
                else
                {
                        defaultStatus = "Session Time: " + mytime + ":" +
mysecs;
                        window.Status += "Session Time: " + mytime + ":" +
mysecs;
                }
                //Code for the redirect
                if (mytime >= timeOut) {
                        window.location 
"http://yourdomain/errorpage.asp?ErrorMsg=" + Errormsg;
                }

        }
        sessionTimer();

hope that helps

I prefer to prevent the session from timing out while the application is on
the screen, by using this line

<META HTTP-EQUIV="refresh" CONTENT="<%=((session.Timeout * 60)-10)%>">

Message #5 by "Bill Todd" <btodd@a...> on Fri, 31 May 2002 00:46:23
A technique I discovered (and I've forgotten where) uses the transaction-
based nature of ASP like so:

Add this as the irst line in the script:
<%@ TRANSACTION=Required%>

(In my case this replaced this line, <%@ Language=VBScript %>, since you 
can have only one <%@ line in a script)

The add a Sub like so:
<%
Sub OnTransactionAbort()
  vPageName = request.servervariables("HTTP_HOST") & 
request.servervariables("SCRIPT_NAME")
  vQueryString = REPLACE(request.servervariables("QUERY_STRING"),"|-
|ASP_0113|Script_timed_out","")
  IF vQueryString <> "" THEN
    vQueryString = "?" & vQueryString 
  END IF
  err = 0
  Set objCDO = Nothing
  Set objCDO = Server.CreateObject("CDONTS.NewMail")
  objCDO.To = "SUPPORT@Y..."
  objCDO.CC = ""
  objCDO.BCC = ""
  objCDO.From = "webmaster@s..."
  objCDO.Subject = "Timeout on SOC page " & vPageName
  objCDO.Importance = 2
  vBody=""
  vBody=vBody & "Script Timeout" & chr(13)
  vBody=vBody & "Server Date/Time: " & FormatDateTime(Now) & chr(13) & chr
(13)
  vBody=vBody & "PAGE/QUERY STRING: " & vPageName & vQueryString & chr(13) 
& chr(13)
  vBody=vBody & "Browser/Op Sys: " & request.servervariables
("HTTP_USER_AGENT") & chr(13) & chr(13)
  vBody=vBody & "Vistor IP: " & request.servervariables("REMOTE_ADDR") & 
chr(13)
  vBody=vBody & "Server IP: " & request.servervariables("LOCAL_ADDR") & chr
(13)
  objCDO.Body = vBody
  objCDO.BodyFormat = 1
  objCDO.MailFormat = 1
  objCDO.Send
  Set objCDO = Nothing

  response.redirect "http://<INSERT YOUR BACKUP SERVER DOMAIN HERE>" & 
request.servervariables("SCRIPT_NAME") & vQueryString

end sub
%>

Since a timeout causes the asp transaction to abort, the logic in the sub 
will be executed. You can code whatever you like there - I set it up to 
send me an email with the timeout details and redirect the user to a 
mirror site.

If you have problems contact me off-list at webmaster@a... since I 
don't always follow the threads here.

 Bill
