ASP.net 2.0 preset cookie_ practical tips

This morning in the foreigner's blog to see this statement, may wish to pay attention to:

If you use FormsAuthentication in asp.net 2.0 and you set the cookie to a persistent state, the duration defaults to 30 minutes, not the 50 in ASP.net 1.1, because 50 is too unsafe, Your computer will be sold by someone. If you want to change, you can use the Timeout property to change

<authentication mode= "Forms" >

<form loginurl= "Login.aspx" timeout= "3600"/>

</authentication>

If you do not change the Timeout property, when you use the login control for ASP.net 2.0, even if the user chooses remember ME, the user will have to log in after 30 minutes.
