I have an application which has a Master Page. My startup page is default.aspx and in my web.config, I have <forms loginUrl="~/ContentPages/login.aspx" />. For all anonymous users I am redirecting them to login.aspx.

On my Master Page I have a LoginStatus. So if the user signs out, the login.aspx is displayed with my Login control. This control also has "Remember me" which I check while logging in. If I close my browser and rerun my app, I get default.aspx with the themes of master pages applied correctly.

If I log out, I am redirected to my login.aspx page (as expected). But this time all my Master Page settings are lost. None of them are applied to login.aspx.

Update:

Looks like themes are not being applied to unauthenticated user. Is it true? If Forms authentication is turned on, will the Theme apply to loginURL?
