Can I change the FormsAuthentication cookie name?
You can adjust it in your web.config file:
<authentication mode="Forms"> <forms name=".CookieName" loginUrl="LoginPage.aspx" /></authentication>
Yes you can specify the cookie name in web.config on forms element under authentication element.
<authentication mode="Forms"> <forms name="RoleBasedAuthenticationCookiename" loginUrl="~/Login.aspx" defaultUrl="~/Default.aspx"> </forms></authentication>
