Forms Authentication and Security token in URL

Ok, here's the question...

After I make the following calls from the login page....
Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, EncryptedTicket));
MobileFormsAuthentication.RedirectFromLoginPage(LoginName,true);

For a single protected page, is there a way to stop the server from attaching my
security token/cookie to EVERY url and/or only apply the token to
the links that are actually contained within my own site?

Thanks in advance,

Mark
