Do I need to delete my cookie before re-adding it?

Every time a user visits a particular page, I'm using the code below to add
a cookie that expires in 1 day.

My question is, a user may visit this page a few times within one day.
Before adding the cookie each time, do I need to delete the previous cookie?
Or will the new cookie just overwrite the old cookie? I'm trying to avoid
having multiple cookies on the user's machine -- just one. FYI, the cookie
"name" will be the same every time.

==========
Dim objCookie As HttpCookie
Dim ts As New TimeSpan(1, 0, 0, 0)
Dim dt As DateTime = DateTime.Now()

objCookie = New HttpCookie("cookie1", "value1")
objCookie.Expires = dt.Add(ts)
Response.Cookies.Add(objCookie)
==========

Thanks in advance,
Ben

Hi,

Your idea is good. However, my cookie is set to expire in 1 day. When the
user visits this particular page, I want to renew the cookie so it won't
expire for another 24 hours. This is why I think I need to re-create the
cookie. What's the best way to do this? If I re-create the cookie, will it
just overwrite the old cookie? Or do I somehow need to delete the old
cookie, then create a new cookie? If this is the case, I'm not sure how to
delete the old cookie.

Thanks again,
Ben
