thanks, it works fine for not authenticated required pages... but when I want to sign out from an authenticate required page (like user profile) it goes to this link that is not right:
http://localhost:10351/KCMS/Logon.aspx?ReturnUrl=%2fKCMS%2f%D8%B5%D9%81%D8%AD%D9%87-%DB%8C-%D9%85%D9%86.aspx
and the eror is "The resource cannot be found."
how can I lead user to Home.aspx when he sign out from an authenticated required page?
