Cookies Expire And Time Zones
I was wondering if anyone knows how to get the current time of the user's timezone in an asp page. Currently I am trying to do some frequency capping in an advertising system i am working on and i want a cookie to expire at the end of the day, in Pacific Standard time.
What is happening now is the cookie is expiring whenever the day ends on the users computer, but i want it to expire when the day ends in our time zone. Any ideas on hwo to do this?? Is there a function i can call to get the users current time based on their timezone?

I need to know how can I inster dates and hours according to the time zone where the user is. For example, I'm on Argentina but the server is at the US. So I'd like to know how to save the time & hour, just like the now function, but in Argentina, although the server is in the US.

I am currently working on a realtime chat project using ASP. In my system a User lets say 'X' has to request for a chat session with say a user 'Y' and Admin checks it and Approves if a valid response.
Now my problem is if user X is from Time Zone 'A' and if user Y is from another Time Zone, My system is gonna have a bad time. So if any one previously worked in such projects please advice me how to handle this situation. Please advise how to time Zone Calculations also.

I have an ASP app that works as an online time clock. The
user logs in and clocks in and out and the app records the
time punches in an access 2000 database. My problem is
this. I just setup a user in the central time zone and
they have reported that when they use the online time
clock, it saves the time as eastern time instead of
central. How can I make the software know which time zone
the user is in?

Some of our web site users are experiencing a strange behavior of IE 6 (Sp1 or not). It looks like their ASP Session Cookie expire before time.
Here are some details. The user connects to our web site and we keep his ID in the Session object. At the beginning of every page, we check the presence of this ID and if it is missing, we redirect the user to the connection page.
Somewhere in the site, we create a temporary cookie. At some point, this new cookie is deleted with the following ASP code :
Response.Cookies(STR_FICHR_TEMN_CONTX).Path = "/"
Response.Cookies(STR_FICHR_TEMN_CONTX) = ""
Response.Cookies(STR_FICHR_TEMN_CONTX).Expires = CDate
("2000-01-01")
When the user clics on an hyperlink, he is redirected to the connection page because his ASP cookie is no more (I have verified that in our IIS log : there is no request
logged after the execution of the above code).
Any ideas ? Could this be an Internet Explorer bug ?

i want to increase my session time so that it does not expire till the user closes the site.
i have written in global.asa file the following code:
<SCRIPT LANGUAGE="VBScript" RUNAT="Server">
Sub Session_OnStart
Session.Timeout = -1
End Sub
</script>
but it doesnt work and my sesion still expires.

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.

understand that when one closes the browser, the session gets killed in ASP,
i encountered a scenario, where even after the browser was closed, the session was active, let me explain, i have written a code to check if the session variable contains the loginname then i am allowing access to a certain asp page to the user.
the code worked. thereafter i closed the browser, opened the browser again and accessed the same url, surprisingly it allowed access to the page and did not ask me for the login name, clearing the cache also did not help.
Further, I need to update some table as well when the user closes his browser window (an update query to set the flag to 0 for tracking user status). How can I do this. A sample code will be highly appreciated.!
Lastly, when the user clicks the logoff button, he successfully logout , but he can come back with the back button on the browser. Is there a way to prevent this,that is, once the user logout and tries to come back, he SHOULD NOT be allowed to do so rather he should be redirected to a page where he can login again.

I've searched the net for ways to expire a page immediately, so when the
user hit 'Back', they receive the "Page Has Expired" error page and I've
seen a number of posts on how to do it - with the code below:
<%
Response.ExpiresAbsolute = #1/1/1980#
Response.AddHeader "cache-control", "no-cache"
Response.AddHeader "pragma", "no-cache"
%>
However, when I try using this code, nothing happens, when I click 'Back',
it simply takes me back to the previous page. The "Expired Page" error page
should display, correct?

Whenever password is expired & force user to change NT password for the web server, it seems to be assumption that asp application gives "interanal server error". Is it true that forcing user to change password will generate "internal server" error? BTW..this is caused in our intranet site and it is NT authenticated site.

I want to expire a cookie collection in my asp page and I gave it like this;
Response.Cookies("whereq").Expires = Now()
and this "whereq" collection has 50 keys. The problem is my cookie didn't expire from the above code. I hope there should be a way to do so without writing 50 expire lines.

i have 2 application variables called totalAdminLoggedIn and totalUserLoggedIn
when ever an admin login, I increment the totalAdminLoggedIn value by one
and when a normal user logg in, the totalUserLoggedIn value will be incremented by one.
how can i change the values when the session expire ? i can reduce the value manually when they logoff like:
if session("userCategory")="admin" then
Application("totalAdminLoggedIn")=Application("totalAdminLoggedIN")-1
elseif session("userCategory")="user" then
Application("totalUserLoggedIn")=Application("totalUserLoggedIn")-1
end if
session.contents.remove "userCategory"

How does the expire date work setting it server side with asp.
I know with javascript setting it client side it will be set to the clients
local time, and therefore expire when the clients local time reaches the set
expire-time.
But if it is an expire time set on my server in California, and the cookie
is put on a computer that is running on London Time, and the expire time is
set at the server as 20 minutes from now, the London computer will think
that the cookie has expired 7 hours and 40 minutes ago, right?
How does this actually work? Is it proper to just set my expire time as:
dtmExp = DateAdd("n", 20, Now())
Response.Cookies("MyCookie").Expires = dtmExp

I've created an admin side for my ASP site and I use session vars to provide
page security.
Just as a bit of advice, I want to know if I should expire each admin page
so that others can't bring them up. I know the session var check will
bounce them back to the login page, but I'd rather they didn't even see this
page if they aren't authorised.
