Non Persistent Cookie In A Web Form.

Im using classic ASP (3.0) and I have a web farm with 2 webservers
(webserver A and webserver B, both windows server 2003). I do not want
to store any client specific information on the webserver (therefore do
not intend to use the session object- as you cannot gaurantee which
server the user will go to). I want to store a small value (e.g. a Y/N
value or an Id) on the client machine for the duration of their
browsing session, hence I want to use a non persistent cookie (in
client memory) not a persistent cookie that will be written to disk.

Q. Therefore if I create a non persistent cookie (i.e. it resides in
the client browsers memory) and set this when the user was on webserver
A, can I read the value server side on subsequent requests even if the
user is redirected back to webserver B? As the webservers are part of
the same domain name Im assuming I can..?

Q. Using non persistent cookies (in client in memory) im assuming the
session Id that gets created has no use, as I am using client side
storage, hence it is worth disabling this on the webserver for
performance reasons?

Q. Is there anyway using non persistent cookies that a user can see the
values of this cookie client side, are their any downloadable tools for
example they can run?

Im aware of the issues with size of using cookies and users can disable
them, my question is more related to using them in a web farm. Im also
not intended in the short term to upgrade to asp.net as Im aware there
are alternatives for state storage in this. Hope someone can clarify
these points for me. Note: I see many articles talking about cookies
but none relating to web farms, those that do talk solely about the
session object (Server side), none really go further to talk about (non
persistent / persistent cookie usage with web farms client side.

Persistent Values?

I'm a (moderate) newbie to and I'm building an ASP/VB db-driven site where the user selects a brand from a menu, this determines the contents for another menu with models. Selecting a model displays details about that model. Nothing too original here Its a small low traffic site with no ecommerce elements - just window shopping.

My questions is : I need to know on all pages what the current brand and model are (and modify these when the user changes them).

From what I understand there are 3 (?) methods: server vars, session vars or hidden fields. Which should I use for this purpose and can anyone point me to some good related examples/tutorials? (I've read the stuff on this site of course).

Response.cookie In Session_onstart Event And IE 6.0 Cookie Acceptance

When I set a cookie in global.asa in the sub session_onstart, even if
I have "privacy" in IE 6.X set to "block all cookies" the cookie is
still set, and I can get it on other pages.

I can't find an article that addresses this as a specific issue. Why
does the browser get the cookie when it is set in the session_onstart
event even when I have "block all cookies" set?

How To Set Cookie To Nothing?

The problem is that the code for "change_school.asp" takes the user right to "portal.asp". I checked the code of "change_school.asp" and it does indeed set a cookie value for "school", but for some reason "default.asp" is still finding the old cookie stored and then redirecting...any ideas guys?

'code for change_school.asp...clears the cookie "school" and redirects to page (default.asp) where user can select a new school
<% Response.Cookies("school")= ""
Response.Redirect "default.asp" %>

'code for default.asp which allows user to select a new school, and if the cookie "school" has some value then they are redirected.
<%
If request.cookies("school") <> "" then
Response.Redirect "portal.asp"
end if

Cookie And SQL?

On this website i am building it has password protection on certain pages. So i have a "login" portion on the right side of the page, that is shown on every page. When someone logs in is it possible to change that little section to just say Welcome so and so? Instead of having the username and password form with submit button?? Or is this something that requires some java to hide it?

Part II
When someone logs in i want them to recieve a cookie, in that cookie i want it to contain the person's name (wich i want the to be put next to the "welcome back on part I), email address, and up to four other numerical values. (some people will have greater access to sections of the site depending on who they are)

Is is possible to grab this information from the SQL database and put in the cookie? If so can anyone please show me, point me in right direction, ect?

Cookie Value

I'm using FrontPage Database results wizards to retrieve data from Access. I have a cookie containing a number I'd like to insert in a custom query. Whenever the page opens, I want the query to run using the value in the cookie.

I’m a little worried, do you know how spiders work with regards to this sort of thing? My site gets some traffic due to it being spidered by the likes of google and I don’t want to loose that flow.

If I use this at the entry point of my site to redirect browsers with cookies turned off to a page telling them to turn them on will that stop the spiders?

A Cookie Disappears, But Not All Of Them

I have a problem with a Cookie in an ASP page. Without any apparent reason, one of the Cookies disappears, but the others are ok.

I'm at Page1, a link goes to Page2. Page2 redirects to Page3 and Page3 redirects to Page1. When I'm back to Page1, sometime, one of the cookies don't exist anymore... But the others are there! The disappeared Cookie isn't always the same, in the 18 Cookies that I have.

The environment is composed of 4 clustered servers. Page1 is SSL, but not Page2 and Page3.

I don't have more than 4KB (1.86KB to be more precise) of data and I don't have more that 20 Cookies on the same domain.

I added the following code:

Cookie Testing

I need to revisit cookie testing. On the home page and every product page I
write a cookie. I do this because some users enter by direct links to
product pages.

<%
Response.Cookies("cookietest") = ("49")
Response.Cookies("cookietest").Expires = Date + 2
%>

On the cart page I test for the cookie...

<%
If Request.Cookies("cookietest") <"49" Then
Response.Redirect("err.asp?e=1")
End If
%>

I have a user that insists he has cookies enabled, yet he keeps getting
redirected to my error page which suggests he does not have cookies enabled.
What could cause this? Is the above too simple for all circumstances?

Is there more extensive code that I could setup on a hidden page where I can
send users to get read out on how they actually have their browsers setup?
i.e. Run a test on their browser and the results are emailed to me.

Cookie Poisoning

I have created a page where i got sth like this:

end if

(I will try to explain as easy i can), so in the login.asp using a .mdb i get the username and check with the password, and putting the username in the cookie in this case called example, but using some cookie poisoning i can be anybody logged in, even sb out of the table of users, i didn't use the session object, i wanted to use a cookie because i got curiosity and i didn't understand what is the difference, and actually i don't understand so much...anyways i got 2 questions, how i do sth for protect the cookie for cookie poisoning and what is the difference between the session and the cookie (from the little what i know is that the session is a predefined cookie that has some encrypting stuff and that so on and got some properties, methods right? and the cookie is just a information holder without any extra stuff as the session object has, am i right?)

Cookie Problems

I''m having a problem with cookies that is driving me insane :).
- If a user comes to http://domain.com and a cookie is set for them, then the user for whatever reason jumps to http://www.domain.com one of the 2 happens:

1) The cookie we set can not be read (expected), but then a new one can not be written ether (I looked at the server headers and although the cookie information is sent, IE ignores it).

2) The cookie from http://domain.com can be read, but you can not write to this cookie. Same here cookie is sent back from the server but IE ignores it.

Now, if its the other way around. If a user comes to http://www.domain.com, a cookie is set, then he/she jumps to http://domain.com:

The cookie can not be read (expected), but a new one can be written (as it should be).

So after driving my self insane, i whent out and tried it out in other servers to see if it was true. I tried 4 different sites which used cookies (for shopping carts). I did the same tests, (Go in via domain.com, add something to cart, then, jump to www.domain.com, cookie would not be overwritten. Then did the other way around, everything worked fine.)

'Cookies On

But I only ever tested it in Microsoft Internet Explorer 6 though not sure. Anyway with Microsoft Internet Explorer 5.5 SP2 Len(Session("nc")) <> 0 always whether cookies are on or off. Can anyone suggest a better cookie test that will work in most browsers?

Reading A Cookie Value?

am trying to create a login page for the first time, I have a login page, validate login page and if the password is correct it takes me to the first page.

I have customized this code someone else created,but what I have a problem with now is I need to log who submitted that data and that is why I am trying to read UserName cookie so I can later match that data.

This is the error I get which is telling me that it is reading the cookie since this is the UserName I am logging in with
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name 'boxhill'.

but I can't see what is wrong, and there is not much out there for this kind of error.

So I can login successfully but now i need to read and dispaly that cookie and then insert the value of the cookie but,but don't worry about that now, just trying to give you the full picture.

So this is the code for reading the cookie ...

Cookie.Path

I'm writing an ASP validation script that uses a cookie that is created by a user validation page and has a single value. This site will be used only under Internet Explorer 5 and more recent.

My problem is that the page called after the cookie creation can't read the cookie unless I set the Cookie.Path attribute to "". All the documentation that I found about it is very brief, don't explain how it really works and if there's any kind of "side effects". An even stranger fact is that some people of my team can read the cookie without setting the Cookie.Path attribute.

Can anyone tell me how the Cookie.Path really works or witch browser settings make it needed (or not)?
