How do I pass session variables from one ASP page to another ASP page?

The session variable will be available from page to page as long as the worker process does not reset.  Just set the session then use it on subsequent pages.

PAGE 1
Session("sessitem_name1") = "abc123"


PAGE 2
response.write Session("sessitem_name1")


You may be better off to use an encrypted cookie though.

fyi, your errors sound like something else is wrong.

You can also combine your session variables like this.


PAGE 1
x = "abc"
y = "123"
z = "xyz"
session("test") =x&"|"&y&"|"&z

PAGE2
arrayTEST = split(session("test"),"|")
x = arrayTEST(0)
y = arrayTEST(1)
z =arrayTEST(2)

response.write y

so the article you posted looks like it applied to asp .net, which is completely different from classic asp. in all of my experience, I've never had an issue passing session variables in the manner you are, so your problem isn't the sessions,.

it looks like you have a permissions issue. make sure your IUSR and NETWORK_SERVICES accounts have access to the folder you're trying to access.

This piece of code is wrong

(Response.Redirect("~/default.aspx", false);). Tried that and get:
Microsoft VBScript compilation  error '800a0414' 
Cannot use parentheses when calling a Sub 
/membership/joinRenew/membershipSession2.asp, line 2266 
Response.Redirect("membershipSelect_R2.asp", false)

Select all Open in new window

Loose the false and semi colon  Response.Redirect("membershipSelect_R2.asp") is all you need.

If I remember correctly you have a very large form.  If you end with all of those in a session, there is potential for problems and concatenating to one session can help.

This is the one that sounds like a permissions error

Microsoft VBScript runtime  error '800a0046' 
Permission denied 
/membership/joinRenew/membershipSelect_R2.asp, line 13 
(Line 13: set textfile = filesys.OpenTextFile(whichFN, 8, 0)%>)

Select all Open in new window

I believe you are right about the article applying to asp.net. But I have found numerous questions on a variety of sites questioning why the values of session variables disappear.

I've tested until I'm blue in the face and can't seem to pinpoint where things are going awry. The code has been running successfully for nearly a year. I was recently asked to make a change, including increasing the number of items that could be purchased (and subsequently passed to PayPal).  By a lengthy and tedious process of elimination, I found that eight items work, but 9+ don't. I know that screams coding error, but I just don't see it.

VBScript that sets all the session variables - code added before Response.Redirect to verify content of variables:
item1                                = Session("sessitem_name1")
quant1                                = session("sessquantity1")
amt1                                 = session("sessamount1")
textfile.WriteLine Now
textfile.WriteLine "<BR><B>1:   </B>  " & item1 & "     " & quant1 & "     " & amt1
textfile.WriteLine "<br>===============================<p>"
.
.
.
item13                                = session("sessitem_name13")
quant13                                = session("sessquantity13")
amt13                                = session("sessamount13")
textfile.WriteLine Now
textfile.WriteLine "<BR><B>13:   </B>  " & item13 & "     " & quant13 & "     " & amt13
textfile.WriteLine "<br>===============================<p>"
Response.Redirect("membershipSelect_R2.asp")
Output:

The first thing that occurs in membershipSelect_R2 logs exactly the same information. The contents of all variables is null:

Are you saying that Response.Redirect should not have any impact on the contents of session variables?  Should Server.Transfer be a consideration?  All of the above referenced logging is made to the text file that is opened in each ASP page. Opening and writing to the file works when I use Response.Redirect. I got the  permission denied when on the log file when I tested with Server.Transfer.

Is there any clue in the fact that the session variables are correct before the Response.Redirect but empty when they are printed out immediately after the Response.Redirect?

Thanks, Scott. As always, I appreciate your insight and help. I resurrected my subscription in the hope that the problem could be solved (I hate not knowing why something doesn't work). You are correct, I do create a large number of session variables. No matter what combination I test with, 8 total cart items is the maximum that will work. The good news is that in the past year, that number, as far as I know, was never exceeded. So 8 it will be. Again, I don't have time for a big rewrite, but in time I will try to change over to the dictionary object (I was not familiar with that). FYI, name, quantity and amount are needed, as that is the format that is passed to PayPal. Each item is passed separately, and PayPal does all the calculations.

Thank you again.

Good news!

I had an old cart doing the same thing by storing the dictionary object to a session.  I still ran into some issue with the session dropping and every once in a while that caused issues that I heard down the line.  Now I simply store the item number and qty in an encrypted cookie.  That way if they close the browser and come back 1 minute or 1 day later, the items could essentially still be in the cart.
