Question

Answer 1

Have a look at your web.config.... there is a section WHICH USERS ARE ALLOWED TO VIEW WHAT RESOURCE and where to redirect those not allowed.

Answer 2

You can set this behaviour in the web.config

Example: (this enables authentication)

<authentication mode="Forms">
   <forms cookieless="AutoDetect" protection="All" slidingExpiration="true" loginUrl="~/login.aspx"/>
</authentication>
<authorization>
   <deny users="?"/>
</authorization>

(the specified path is excluded from authentication. meaning you can access the file/directory without authentication. useful for image, scripts, styles directories)

<location path="login.aspx">
   <system.web>
     <authorization>
        <allow users="*" />
     </authorization>
    </system.web>
</location>
