ONE person gets an ASP error....

Re: ONE person gets an ASP error....

While I imagine you could purposely cause this error for one person if you
really wanted to, i.e.

<%
if request.serverv ariables("remot e_addr") = "192.168.1. 50" then
response.flush
response.redire ct "elsewhere. asp"
end if
%>

I'll assume you're not doing that. Are you buffering? What version of IIS?
IIS 4 (NT 4 with Option Pack) does not buffer by default, where as IIS5 and
over do. Do you have response.buffer = true for good measure? That should
avoid this for all people. Perhaps others are just getting a 500 error,
whereas this user has friendly errors disabled, and no one is reporting the
500 to you. Turning on buffering should solve the problem. I cannot think
of any reason why it would buffer for everyone but one person.

Re: ONE person gets an ASP error....

No buffering (on these pages)....
I understand your hypothesis, but it's not correct in this case
Other users are *not* getting the error... they get the correct page
display.

In fact it is more subtle than this (as indicated in orig. post).. because
the line no of failure is a line that gets executed only on failure of
access - ie if a session value is not set, they are 'Redirect'ed to a denied
page (which is failing for ONE user)!!
BUT they cannot get to even go to the "failing" page *unless* they ARE
logged in correctly....

Huh (!?)... I don't get this.

Re: ONE person gets an ASP error....

Probably she have disabled her cookies, including session cookies, or she is
behind a firewall or a proxy who block them or she is using some kind of
anonymiser software.

In all these cases, she will be in a session-less state: the IIS will be
unable to retain her session's values when going from one page to another
because her session cookie is blocked or otherwise unavailable.

Re: ONE person gets an ASP error....

www.adopenstatic.com/faq/headererror.asp explains why you are getting this
error.

Why don't you post lines 1-21 of the page in question?

Don't put redirects in after some response has been written if you're not
buffering. Or, don't not buffer if you're redirecting after some response
has been written - however you want to look at it.

Re: ONE person gets an ASP error....

" www.adopenstatic.com/faq/headererror.asp explains why you are getting this
error."

Yes, I know about buffering... I explained that in the post.
But code is not writing the headers BEFORE Line 21 (see below).

In addition, there's the issue of 'authorisation' .. (see prev. post)

FYI: here's lines 1-21... (std. Dreamweaver code)

<%@LANGUAGE="VB SCRIPT"%>


<%
' *** Restrict Access To Page: Grant or deny access to this page
MM_authorizedUs ers="1,2,3"
MM_authFailedUR L="AccessDenied .asp"
MM_grantAccess= false
If Session("MM_Use rname") <> "" Then
If (true Or CStr(Session("M M_UserAuthoriza tion"))="") Or _
(InStr(1,MM_aut horizedUsers,Se ssion("MM_UserA uthorization")) >=1)
Then
MM_grantAccess = true
End If
End If
If Not MM_grantAccess Then
MM_qsChar = "?"
If (InStr(1,MM_aut hFailedURL,"?") >= 1) Then MM_qsChar = "&"
MM_referrer = Request.ServerV ariables("URL")
if (Len(Request.Qu eryString()) > 0) Then MM_referrer = MM_referrer & "?" &
Request.QuerySt ring()
MM_authFailedUR L = MM_authFailedUR L & MM_qsChar & "accessdeni ed=" &

Re: ONE person gets an ASP error....

Hmmm. Is it possible that this one user is, for whatever reason, going
through a path in your code branching that you don't expect anyone to go
through? So that, for her only, there _is_ content being written to the
browser before a redirect? Maybe some test code that response.writes a
variable, that you never bothered to comment out because nobody takes
that branch? Or a stray "<" outside of your ASP code? Have you checked
all your include files?

Re: ONE person gets an ASP error....

Is it possible she's bookmarked this page and is going directly there
without going through your login routine?

Re: ONE person gets an ASP error....

I think Sylvain has hit on the answer. She has session cookies turned
off in the browser, so the session get lost each time a new page is
requested.

Re: ONE person gets an ASP error....

You could be right, there. Of course, the bigger issue, in my opinion, is
don't redirect if you're writing a response and not buffering!

Re: ONE person gets an ASP error....

It's a server-side ASP error, and it's not the code? It IS the code. You
have to code for all possible client configurations, and if you do not, and
an error is generated because of it, it's either a problem with the code or
the coder, however you want to look at it.

Re: ONE person gets an ASP error....

Hardly a 'bigger issue'... there are 400+ users on the site... no
problems... *ONE* person is getting this anomally, which is caused by
(maybe) session cookies.

There are plenty of Redirects on the site... none are causing a problem to
anyone else!
So no - not a 'bigger problem' at all.

But haven't ranted a tad <g>.... my code up to the reported problem line is
included below - for my sake, can you point out *where* I am 'writing a
response then redirecting'?
(It is standard Dreamweaver, btw)

<%@LANGUAGE="VB SCRIPT"%>


<%
' *** Restrict Access To Page: Grant or deny access to this page
MM_authorizedUs ers="1,2,3"
MM_authFailedUR L="AccessDenied .asp"
MM_grantAccess= false
If Session("MM_Use rname") <> "" Then
If (true Or CStr(Session("M M_UserAuthoriza tion"))="") Or _
(InStr(1,MM_aut horizedUsers,Se ssion("MM_UserA uthorization")) >=1)
Then
MM_grantAccess = true
End If
End If
If Not MM_grantAccess Then
MM_qsChar = "?"
If (InStr(1,MM_aut hFailedURL,"?") >= 1) Then MM_qsChar = "&"
MM_referrer = Request.ServerV ariables("URL")
if (Len(Request.Qu eryString()) > 0) Then MM_referrer = MM_referrer & "?" &
Request.QuerySt ring()
MM_authFailedUR L = MM_authFailedUR L & MM_qsChar & "accessdeni ed=" &
Server.URLEncod e(MM_referrer)
Response.Redire ct(MM_authFaile dURL)

Failure (allegedly) occurs on this last line.

Re: ONE person gets an ASP error....

Yeah, right here:


I'd be willing to bet that include has html in it. Would you just buffer
your damn pages? You're not going to be able to win an argument with your
server and convince it to do something different.
