Remarks: ASP Response Object Cookies Collection

If a cookie with keys is created, as in the following script:

Response.Cookies("myCookie")("type1") = "sugar"

Response.Cookies("myCookie")("type2") = "ginger snap"

the following header is sent:

SET-COOKIE:MYCOOKIE=TYPE1=sugar&TYPE2=ginger+snap

Any subsequent assignment to myCookie that does not include a key would destroy type1 and type2. The following example discards the values type1 and type2 and replaces them with the value "chocolate chip":

Response.Cookies("myCookie") = "chocolate chip"

Conversely, calling a cookie with a key destroys any non-key values the cookie might contain. The following code will discard the value "chocolate chip" and insert the key value instead:

Response.Cookies("myCookie") ("NewType") = "peanut butter"

To check to see if a cookie has key values, use the following:

Response.Cookies("myCookie").HasKeys

If myCookie is a dictionary and has keys, the previous script will evaluate to TRUE, otherwise it will be FALSE.

An iterator can be used to set cookie attributes. The following example sets all cookies in a collection to expire on Dec. 31, 2003:

<%

For each cookie in Response.Cookies

   Response.Cookies(cookie).ExpiresAbsolute = #Dec. 31, 2002#

Next

%>

An iterator can also be used to set the values of all cookies in a collection, or all keys in a cookie. However, when using an iterator to retrieve cookie values, the cookies must have keys or the iterator will not execute. Use the HasKeys property to check to see whether a cookie has any keys. This is demonstrated in the following example.

<%

If Not cookie.HasKeys Then

   'Set the value of the cookie

   Response.Cookies(cookie) = ""

Else

   'Set the value for each key in the cookie collection

   For Each key in Response.Cookies(cookie)

      Response.Cookies(cookie)(key) = ""

   Next key

%>
