Me, My Life and .NET

By default Asp.NET uses Login.aspx as its default Login page. That means if you want to access a page that you are not authorized to access you will be redirected to Login.aspx. Also if you click a Login Status control you will be redirected to Login.aspx.

You can easily override this feature and use a custom page (say Default.aspx) instead of Login.aspx as default login page.

To do so Simply add the following code in Authentication section of web.config

<forms loginUrl="Default.aspx"/>

You can also override other default settings by setting custom values in web.config. Some other default settings are

<forms name=".ASPXAUTH"
loginUrl="login.aspx"       
defaultUrl="default.aspx"
protection="All"
timeout="30"
path="/"       
requireSSL="false"
slidingExpiration="true"      
cookieless="UseDeviceProfile"
domain=""       
enableCrossAppRedirects="false">
<credentials passwordFormat="SHA1" />
</forms>

Change the default value to override the default behavior.

One of the basic requirements for websites is to restrict access to certain pages. This can be easily done using new security API and Role Management features provided in ASP.NET 2.0.

NOTE : Rules defined, follow a top-to-bottom approach i.e. First of all first rule is used then second and so on. For Example in the picture if some one wants to access pages in Administrator folder, First of all .net will check that this user belongs to Administrator Role or not, If user belongs to Administrator role access will be granted else second rule will be checked which says to block all the users. So User who are in Administrator Role will be able to access pages.
