session variable lost after redirec in classic ASP

beetle_jaipur · November 20th, 2008, 12:47 AM

Hi,

i am facing some problem regarding redirection and session variables

after setting session variable, if i redirect the page, all session variables are lost.

tried to find solution over internet but most of the solution are for asp.net, i could not found any solution for classic asp.

if anyone has any idea how to overcome the problem, will be great help.

contact.asp?contactMode= enquiryForm
************************************************** *********
   session("enqName") = request.form("enqWebname")

   Dim RedirectUrl
   RedirectUrl = "contactus.asp?status=success"
   Response.Redirect(RedirectUrl)

************************************************** *********

contact.asp?status=success
************************************************** *********
  dim Name
  Name = session("enqName")

   Response.write(Name)
************************************************** *********

thanks for spending time to reading this problem

all suggestions are welcome

thanks and regards

Are you sure request.form("enqWebname") contains a value?

Session variables arnt that complex. They certainly do not fail when redirecting.

Just before:

session("enqName") = request.form("enqWebname")

write request.form("enqWebname") to the browser to check it has a value

This logic is wrong:

Code:

   <%
    dim naam
    if naam <> "" then
       naam = session("Name")
       response.Write(naam)
    else
       Response.Write("No Session Value")
    end if
%>

Specifically, these 2 lines:

Code:

    dim naam
    if naam <> "" then

Your if statement is always going to evaluate as false because you declare naam without first assigning a value to it so naam is always going to equal an empty string.

In other words, Doug is telling you to swap two lines of your code, thus:

Code:

<%
    dim naam
    naam = session("Name")
    if naam <> "" then
       response.Write(naam)
    else
       Response.Write("No Session Value")
    end if
%>

sorry that was typing mistake here only.

in my code it is
**********
<% dim naam
    naam = session("Name")
    if naam <> "" then
        response.Write(naam)
    else
        Response.Write("No Session Value")
    end if
%>

I guess I have to ask the obvious question: Do you have cookies disabled???

If you disable cookies, session variables do *NOT* work.

hi

what i found that my code is working if i upload it to web server,
not working at my pc,

i have checked that:
server variables get initiated and value exists till i am on the same page

both server variables and request.form shows the value on same page
and cookies are enabled.

is this firewall problem. i am having zonealarm firewall
