<p>Can a cookie be shared between two sites on the same top level domain? Say <code>www.example.com</code> and <code>secure.example.com</code> ?
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</p>

Yes, you can. Use:
```
```
Response.Cookies("UID").Domain = ".myserver.com"
```
```
