asp.net - Cookies and subdomains

Question

Can a cookie be shared between two sites on the same top level domain? Say www.example.com and secure.example.com ? We are looking into implementing a cache for non-secure content, and need to segregate secure content to another domain. What parameters does the cookie need? I'm using asp.net

Answer 1

Yes, you can. Use:

Response.Cookies("UID").Domain = ".myserver.com"
