I use Domain to solve the problem of reading different sites cookie http://www.microsoft.com/china/msdn/archives/library/dv_vstechart/html/vbtchaspnetCookies101.asp ============ ============================================================================================================================================================================================================= ======= You can also use the Domain property to create cookies that can be shared in multiple subdomains. For example, the domain is set as follows: Response.Cookies ("domain"). Value = DateTime.now.tostring response.cookies ("domain"). Expires = datetime.now.adddays (1) Response.cookies ("Domain" This cookie can be used in the primary domain, Sales.Contoso.com and support.contoso.com ==================== ============================================================================================================================================================================================================= This approach is only suitable for sites between the same domain, and cannot simply solve data information between different sites, but this method is very simple, plus a line of code.

Remove the Cookie Supplement: Delete the cookie (ie, the cookie is physically deleted on the user's hard disk). Since cookies is located in a user's computer, you can't delete it directly. However, you can let your browser delete cookies for you. It is to set it to a certain date in the past. When the browser checks the validity of the cookie, this expired cookie will be removed.
