deleting a cookie...

[halukorhan1]

Hi,

I could not manage to delete the cookies on the client when the transaction is over.

The codes given below did not work to delete the cookie.

Response.cookies("sepet")("SID") = ""
Response.Cookies("sepet").Expires = Date() - 15

Even I had tried to change the SID value (assign a new value) in the cookie with the codes given below, but it did not work:
<%
if cint(day(now)) < 10 then
dd = "0" + cstr(day(now))
else
dd = cstr(day(now))
end if

if Cint(month(now)) < 10 then
mm = "0" + cstr(month(now))
else
mm = cstr(month(now))
end if

yyyy = cstr(year(now))

if Cint(hour(time)) < 10 then
hh = "0" + cstr(hour(time))
else
hh = cstr(hour(time))
end if

if cint(minute(time)) < 10 then
min = "0" + cstr(minute(time))
else
min = cstr(minute(time))
end if

'Response.Cookies("sepet").Expires = Now()
'Response.cookies("sepet").Expires = Date() + 14
Response.cookies("sepet")("SID") = dd & mm & yyyy & hh & min & cstr(session.SessionID)

session.Contents.RemoveAll()
%>

Do you have any idea how can I delete the cookie on the client PC?

Any help is appreciated.

Regards!

Haluk

you don't. expire it and empty it.

but deleting is a client side operation

ermm! did you miss the you don't bit ??

the only thing you can do is set the expiry and the browser will clear the cookie on the next occasion that a new cookie has to be added and the maximum number of cookies would be exceeded (browser dependant) .

ASP has no means of accessing the client machines drive. Any client side script operation to delete a cookie would very likely be blocked as suspicious activity.

let's see:
Javscript:
you would have to redirect to a page that had a javascript to search the client hard drive for a file that you don't actually know the name of (only part of it) or the location (depends on the browser) Then delete it. Hmm I can see all the unsafe script warnings and alerts happening as I type this.

lets not even bother looking at Client side vbScript or WSH.
