Can not clear the cookie form another application

[ad]

I use the codes below to clear the cookie["us_id"]:

HttpCookie myCookie = new HttpCookie("us_id");
myCookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(myCookie);

It do well when the cookie is from the web application itself,
But fail to clear when the cookie is form another application, like php.

How can I do?

I had a similar problem once. I just changed the cookie name in my
web.config file to avoid any conflicts. That worked.

Make sure you use the same Domain and Path as the cookie you want to clear.

The domains of both are all null, and the Paths are all "/"

HttpCookie myCookie = new HttpCookie("us_id");
myCookie.Expires = DateTime.Now.AddDays(-1d);

I find there is nothing like these two extensions for debugging this kind of
thing:

What is Gecko browser ?

Not to my knowledge. But a Gecko browser should be part of your debugging
toolbox anyway, if only for testing compatibility.
