Update SharePoint default application pages (AccessDenied.aspx, SignOut.aspx) with your own custom pages

I came across the situation where I need to replace the default SignOut.aspx page with custom page.

The following feature receiver replaces the default SignOut page with a custom one on activation and resets the SignOut page to the default one on deactivation.

[Guid("d8ed5819-b368-493f-a59c-1167c2a63799")]

public class UpdateDefaultPageEventReceiver : SPFeatureReceiver

{

    const string customPage = "_layouts/MyPage/CustomSignOut.aspx";

    public override void FeatureActivated(SPFeatureReceiverProperties properties)

    {

        SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;

        if (null != webApp)

        {

            if (!webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.Signout, customPage))

            {

                //Unable to replace the SignOut page

            }

        }

    }

    public override void FeatureDeactivating(SPFeatureReceiverProperties properties)

    {

        SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;

        if (null != webApp)

        {

            if (!webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.Signout, null))

            {

                //Unable to reset the SignOut page

            }

        }

    }

}

You can also replace other pages which are member of SPWebApplication.SPCustomPage enum. (e.g. AccessDenied.aspx, Confirmation.aspx, Error.aspx, Login.aspx, ReqAcc.aspx, SignOut.aspx etc.)
