How to Write into a Cross-Subdomain Cookie

[flip79]

Hello and sorry for my english, I'm italian...

I manage a site with a normal address like: www.mysite.com
I'm using a cookie to store nicks of my users, with a code like this:
----
Response.Cookies("mycookie").Expires = #January 1, 2030#
Response.Cookies("mycookie").Path = ""
Response.Cookies("mycookie").Secure = FALSE
Response.Cookies("mycookie")("nick") = nick
----

and I'm deleting it, if a user wants so, with:
----
Response.Cookies("mycookie").Expires = #January 1, 2003#
Response.Cookies("mycookie").Path = ""
Response.Cookies("mycookie").Secure = FALSE
Response.Cookies("mycookie")("nick") = ""
Response.Cookies("mycookie") = ""
----
(I know, there's too much stuff in the delete procedure!)

Now I'm going to open some new sections of my site, with subdomain
adresses, like search.mysite.com, shop.mysite.com... and I need that
cookie authentication for the main (www) address is working also in
these subdomains.

I red on the Internet that with the DOMAIN property, I can set my
cookie to make it work for every subdomain, with something like:
----
Response.cookies("mycookie").domain = ".mysite.com"
----

.... and it works!
My problem is when I try to DELETE it: after I set a cookie with
..domain property, it seems to become "read only": any my attempt to
delete (or modify) it seems to be ignored.

Results are the same when I try to write it from the subdomain that
created it (www), or when I try from the "chief" address (mysite.com,
without any subdomain).

Where's my mistake?

Thanks everybody in advance.

Exact code you are using to create the cookie and exact code you are using
to delete it would help.

My guess is that you aren't using .domain = ".mysite.com" when deleting it.
