Cookies And Browsers
I'm coding a shopping cart in asp. I store all info about ordered items, customer's coordonates, etc. into cookies. When the order is complete I use "CDONTS.NewMail" to send an order confirmation's email, where all items and details are listed for the customer. As to retreive all these info a code reads all info stored in the cookies. If a run my code under Firefox and Konqeror , all works well and the sent email contains all info.
So, I wrote a code to read all cookies on the page before opening the page that generates the email to the customer, then when tested, all the cookies and session variables can be read. Under i.e.,if the same code is run in the page generating the email, it returns empty session variables and some cookies are missing or are now empty or can't be read!If it is tested under Firefox and Konqeror all cookies and session variable are stil there.

This problem occurs in classic ASP on a simple asp page I am writing.I am trying to output a random number using VBScript's Rnd() function.Whenever I refresh my browser, the same number appears(0.7055475).This happens in both Internet Explorer and Firefox. This is all I'm doing:
<%Response.Write(Rnd)%>
I have pressed F5 to refresh, cleared both browser caches,and even restarted IIS.I was under the impression that a psuedo-random number would at least change values when I refreshed my browser.Does anyone know what the deal is with Rnd() not producing different numbers?

I have been having problems with Gecko based browsers not redirecting properly.
This is the line of code that does the redirecting:
Response.Redirect ("Validation.asp?BookingNo=1234567")
The Gecko based browsers change this URL to read "Validation BookingNo=1234567" and of course they get a 404 Error as a result. The above code works on every other browser without fault. So why do Gecko based browsers have a problem. Is Gecko just nother work for this software.

Go to this page:
http://support.microsoft.com/defaul...kb;en-us;224979
And then use their second example the clientcap.htm and clientcap.asp section. Then fire up clientcap.asp and watch the Microsoft Internet Explorer browsers crash.

we are using internet explorer 6, reading information from w2k iis asp. users
are opening two browsers so they can keep two sessions open with different
information. It is rare, but sometimes the the non-active browser will use
the session varibles from the active one. We have deleted local content and
cookies with no affect. any thoughts?

1) I have the following html code on the server:
<HTML>
....
.....
<BODY>
<A HREF = http://MyServer/MyDoc.doc> Click here to see the document</A>
When I click on the link How Internet Explorer understand that it's a Word
Document and It's necessary open it with Microsoft Word ? Is The extension
to give the necessary information to Internet Explorer ?
Where does IE look for the application to use to open the file on the server
? On the local registry ?
I have tried to rename Mydoc.doc in MyDoc.pdf and I have called
http://MyServer/MyDoc.pdf and the browser has opened Acrobat Reader but the
binary format is for Microsoft Word.
Does the Browser User an Http_Header sended automatically ? (for example
HTTP_FILE_NAME....IF IT EXISTS)
2)Now I have the following link:
http://MyServer/ReturnMyDoc.asp
It returns the binary data of MyDoc.doc file. Now I want to say to the
browser that the file is called MyDoc.doc (I don't want to use Content Type
= ms-application/msword) : is there a header to say this to Internet
Explorer ?

In my Session_OnStart in Global.asa, I am setting some cookies. One
of them, I set as follows:
dim UserID
UserID = Request.ServerVariables("LOGON_USER")
Response.Cookies("User")("ID") = UCASE(UserID)
When I immediately log the cookie value retrieved from
Request.Cookies("User")("ID") into the Windows Event Log, I get the
correct value. However, when I try to retrieve the cookie on the home
page of my application using the same code,
Request.Cookies("User")("ID"), it either cannot find the cookie or
cannot read the value. I am retrieving the cookie before all HTML
headers are written. It is my first statement on the page after
Option Explicit. I have even compared the session IDs. The SessionID
created in the Session_OnStart is the same value as the SessionID on
the home page.
I have read that the Session_OnStart only has access to the
Application, Session and Request objects. It does not explicitly say
that it does not have access to the Response object. Also, I was even
able to use Response.Write's in Global.asa to print out the values
although it looked like it had also stopped the session after I did
so. Cookies are definitely enabled on my machine. I have even tried
setting the session cookie's expiration to be persistent for a few
days to see if it was perhaps expiring before I was able to read it
but this did not work either.
Is there something preventing cookies to be created in Global.asa in
the Session_OnStart sub? Is the Response object not available???
Please let me know if anyone else has had this problem or solution.

I am creating a user tracking app that tracks a user one of two ways...
1)First Method is cookies
2)Second Method MS SQL DB
I first check if the users browser accepts cookies if not I go to the db. If the user accepts cookies then I check for a specific crumb if it does not have the value I am looking for I kill it and rewrite it. This is working fine (im in the middle of testing it). The problem is I decieded to test the script with NN7 and not turn cookies off but block cookies from my site and all fell apart. The condition that I have set (detect if cookies are enabled) does not stop the script from trying to set a Session Variable because the browser accepts cookies and to keep a long story short it goes into an infinite loop because the script is looking for a Session value and Its not being stopped becaues the script thinks its alright to write cookies! Is there a way to detect if a user has your sites cookies blocked? This is important because Server.CreateObject("MSWC.BrowserType") will return .Cookies = True and you will not know that your script is not executing properly because a user has your sites cookies blocked but excepts them elsewhere...

I've built a website which requires a user to log-in to access the site. I have already built a page that enters their details into a db (register.asp), and another page where the user enters their email address (the log-in ID) to actually log-in (login.asp).
How can I use a cookie to automatically log a user in??
More specifically, what are the commands to set a cookie (upon successful registration) and access it (upon re-logging in)?

Hey i've spent the last few hours trying to work this problem out about cookies.
When a user logs in to the site the login.asp page checks the database to see the personal page that the user re directs to e.g if bob brown logged in he would be redirected to bob.brown.asp. This is stored in a field in the database table along with the username and password.
i would like to put a cookie onto the users computer that remembers the url they were redirected to so when they press the main page button it would look for the cookie and see what url they are meant to be redirected to and take them there
My current login system is this ....

I'm trying to load up a page through my asp page and get the cookie from that page so that I can use it later on when it needs to have it to access other parts of the site.
Basically the asp page is going to act like a browser and store the cookie from the other site, then send that cookie back when the asp page goes back to the other site again.
The problem is, I can only seem to access my own cookie. I didn't run into this problem when I was doing a similar thing inside my .cs scripts that were run by the server, as I suppose they were not coming from the actual domain that my page is running on (and thus, wasn't getting everything trampled by local cookies).
Is this possible, or should I just give up on it now?

im building a site for a few doctors surgeries. the user is able to see what appointments are available and then book that date/time. i have a table (in my db) of dates/times and a checkbox to say whether the time has been booked or not (and display only times that havnt been booked). i was going to have the user add the time to a "cart" and then check the "booked" checkbox in my db when theyve paid for that appointment. but if i have lots of people looking at the site at the same time, then they may be able to see times that are just about to be booked. i think a better way is to have the date/time stuffed into a cookie which expires after 5 minutes. so when a user adds a time to their "cart", it will say something like: "this time will expire in 5 minutes until you book it or re-add it to your cart". does that make sense?
how can i do this with server-cide cookies (im using jscript)? can anyone think of a better way to do this?

I need to set a cookie on a user after they have logged in. I want to
use just the user's login name , since that is a unique field.
If rsPersonIDCheck.EOF Then
Session("blnValidUser") = False
Else
Session("login") = rsPersonIDCheck("login")
but:
set Cookies("User") = Session("login")
seems not to be creating the cookie

I found that a number of my sites that send email using CDO failed withing the past 30 days. Consider the following. I know its not the best coding practice to open and close the connection so many times but Im curious why this would all of a sudden become an issue.
1. Have a few large sites essentially all variables such as SMTP server are set using cookies so I can deploy multiple sites quickly.
2. Within the site email appears to work correctly across all pages with 1 exception.
3. The exception is below, Im wondering if it has to do with cookies having to be retrieved multiple times from the client machine
--Call db run search loop data build array
--Based on data in array call another search alter and finalize array
--Do while <= uBound(myArray)
--Call Email sub (from,to,sub,body) ' Sub contains a request cookies for SMTP server.
--Loop
Doesnt matter if its 2 or 50 emails always fails when using request.cookies to set the SMTP in the sub. Works fine if I hard code the IP. This same sub is used multiple times throughout the website and works fine with cookies.
Just curious why it needs might need to be hard coded in the loop. Has been running for about 6 months fine and have recently started noticing failures.

I started using the following code, although, I have a feeling it is not working. Also, do I have to place the same code on all accessed pages? Code:
<%
Response.Cookies("ExpCookie") = "Expiration"
Response.Cookies("ExpCookie").Expires = DateAdd("d", 1, Now())
Response.Cookies("ExpCookie").Secure = True
Response.Cookies("LastVisit") = Date & " " & Time
%>
I am new at all of this, I can understand that this cookie will expire an hour after being access on a given day (is that right?), and it will create the cookie with the printed date and time of access. how can I make sure cookie expire on time.

I need to build my own simple cart that writes to cookies only. I can write
and read cookies, but don't have a clue as to how I can add multiple
products, change quantites, etc. All I need is a cart that stores
information in cookies and the user prints their order. That's it. Where can
I find such information?
