Session Variable gets truncated and drives me crazy

D

doltharz

Please Help me

i'm doing something i though was to be REALLY EASY but it drives me
crazy

The complete code is at the end of the email
(i mean newsgroup article),

i always use Option Explicit
and Response.Expires=-1,
there is NO INCLUDE at all,
no side effect from any other asp page,
no global.asa of nothing like that.
It's on MY IIS 5 server
hosted on a Win2000 server SP3.
I'm using IE6-SP1

Here it goes for step by step explanation:

I call http://192.168.0.102/Page.asp&driving=me&crazy=true

I write down session variable content

Response.Write Session("DoltharzURL") & "<BR>"
<!-- THE NEXT LINE IS REALLY BLANK -->

(( Till it's the first time, there is nothing here ))

<!-- THE PREVIOUS LINE IS REALLY BLANK -->
i put the current page address with its querystring in a session
variable

Dim tmp
tmp = Request.ServerVariables("SCRIPT_NAME") & "?" &
Request.ServerVariables("QUERY_STRING") & ""
Session("DoltharzURL") = tmp & ""

The & "" at the end is to be sure the data is really a string and not
a reference to an object even if it's not necessary till it's already
a concatenation of something else... too much can't hurt.

Then i write down session variable content, just to be sure it's realy
in the session variable and it's really there.

Response.Write Session("DoltharzURL") & "<BR>"

/Page.asp?driving=me&crazy=true

Then i REOPEN the SAME page which does write down the session variable
content

Response.Write Session("DoltharzURL") & "<BR>"

/Page.asp?

Why is the querystring gone????????????

Even stranger, if i set the Session Variable content this way
Session("DoltharzURL") = "BEGIN" & tmp & "END"
I'll end up with
BEGIN/Page.asp?END
Even if all the time Response.Write folling the Session Variable
content definition gives me the right content

Going even further, i manually set the content to
"/Page.asp?driving=me&crazy=true"
without calling any other function (ServerVariables) and here it's
working fine.

So i said to myself, there is a {BEEP} \0 at the end of that {BEEP}
Request.ServerVariables("")^so i've type a function that write down
the content of the string byte by byte giving all ascii code...

<%
For i = 1 to len(arg)
Response.Write i & ", " & mid(arg,i,1) & ", " & asc(mid(arg,i,1))
& "<BR>"
next
%>

it gives me (fake one)

27, =
28, t
29, r
30, u
31, e

with no gap in the char count 1..2..3..4..5.. ... ..31..32
there is no \o between "/page.asp?" and "Drime=me&Crazy=true"
So i though it was the "?" so i replace it by "XYZ" to end up with
/Page.aspXYZ

The variable is called DoltharzURL which i assumed isn't a reserved
keyword, if it is... i'm a very lucky guy.

Please Help me

Hi

It seems we have the same problem, read my post (4 posting below you) "the
value of session variables gets lost". It is a strange problem.

To drive me a little bit more craze but maybe to help some of you to
pin point the problem:

Remember that those are not scientific bullet proof copy/pasted code
but human typed article... dont flame if a typo makes it way to you.




This one works when not using the QUERY_STRING
"/page.asp?80" makes it way
<%
Dim tmp
tmp = Request.ServerVariables("SCRIPT_NAME") & "?" &
Request.ServerVariables("SERVER_PORT") & ""
Session("DoltharzURL") = tmp & ""
%>

This one doesn't work when using the QUERY_STRING
Only a "/Page.asp?" makes it way
<%
Dim tmp
tmp = Request.ServerVariables("SCRIPT_NAME") & "?" &
Request.ServerVariables("QUERY_STRING") & ""
Session("DoltharzURL") = tmp & ""
%>

This one doesn't work when using the QUERY_STRING
Only a "?" makes it way
<%
Dim tmp
tmp = "?" & Request.ServerVariables("QUERY_STRING") & ""
Session("DoltharzURL") = tmp & ""
%>

Maybe the problem is the QUERY_STRING server variable and not the
Session Variable.

Hope that helps those who are tring to help us ;)

Have you tried "View Source" in the browser? Sometimes, because of HTML
formatting issues, the output of an ASP page differs from what the
browser presents.

Good Luck,

I called it 5 times - no difference.

You need to call the page TWICE.
The second time, the session variable content is not what it is
expected (for me)

it's not a formatting issue but really a "NON EXISTANCE" issue
it's a wise guess till & is an escape code but... already checked that
one... thanks...

&param2=something produces something like
¶m2=something

It seems that only ServerVariables("QUERY_STRING") produces that ,
i've tried with some others like SERVER_PORT or SCRIPT_NAME

after more tests
i realised the probleme only occured when there is some HTML code
before the critical code and only with ServerVariables("query_string")

take a look at this sample

try it with and without the HTML code

%>
<!DOCTYPE>
....
<BODY BGCOL...>
<%

= Code goes here = = = = = = = = = = = = = = = = = = = = = = = = = = =

<%
Option Explicit
Response.Expires=-1
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<HTML>
<HEAD>
<TITLE></TITLE>
<META NAME="Generator" CONTENT="TextPad 4.6">
<META NAME="Author" CONTENT="?">
<META NAME="Keywords" CONTENT="?">
<META NAME="Description" CONTENT="?">
</HEAD>

<BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#FF0000" VLINK="#800000"
ALINK="#FF00FF" BACKGROUND="?">

<%

Dim tmp
tmp = Session("DoltharzURL")
Response.Write "tmp=" & tmp & "<BR>"
Response.Write Session("DoltharzURL") & "<BR>"
Response.Write Session.SessionID & "<BR>"

'tmp = Request.ServerVariables("SCRIPT_NAME") & "?" &
Request.ServerVariables("QUERY_STRING") & ""
tmp = Request.ServerVariables("SCRIPT_NAME") & "?" _
& Request.ServerVariables("QUERY_STRING") & ""

Session("DoltharzURL") = tmp & ""
Response.Write "tmp=" & tmp & "<BR>"
Response.Write Session("DoltharzURL") & "<BR>"
Response.Write Session.SessionID & "<BR>"

%>

</BODY>
</HTML>

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

I'm not sure what you mean by "HTML code". Show us the version that works,
followed by the version that doesn't work. I know that will make the post
much longer, but it will eliminate the guesswork.

OK - this got to me too late for me to do anything with it today. What I
would suggest is that you remove lines one-by-one from the page that does
not work until you discover exactly which line is causeing it to fail. I
suspect that it's that DOCTYPE line, myself. Any idea why you need that one?

it's included in the TextPad blank page pattern and i was also willing
to create a CSS/W3C Validated Page.

I think i got it...

<BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#FF0000" VLINK="#800000"
ALINK="#FF00FF" BACKGROUND="?">

BACKGROUND="?" seems to cause the problem
BACKGROUND="" works just fine
