cookies will work everywhere?

i have the following method to write cookies

Code:

---

Response.Cookies["WebLog"]["User"] = nickTxt.Text;
Response.Cookies["WebLog"]["Pw"] = pwTxt.Text;
Response.Cookies["WebLog"].Expires = new DateTime(9999, 12, 25);

---

this will save cookies untill 12/25/9999 but..this page is Login.aspx..will Main.aspx benefit from this same cookie too?

Cookies aren't local to a page if thats what you are asking? So you should be able to reach the same cookie on different pages.
