Secure webApplication

I am building an application(asp.net) with o开发者_StackOverflow社区nline payment so i want to make these payment page SSL enable. How can i do that.. Help me..

Thanks

Create class similar to

public class SecurePage : Page
{
    protected override void OnInit( EventArgs e )
    {
        //retrieve appsettings value. set to false for localhost or dev environment
        var sslRequired = bool.Parse(WebConfigurationManager.AppSettings["Security-SSL-Required"] ?? "true");
        var currentUrl = System.Web.HttpContext.Current.Request.Url;

        if (!currentUrl.Scheme.Equals(Uri.UriSchemeHttps, StringComparison.CurrentCultureIgnoreCase) && sslRequired)
        {
            //build the secure uri 
            var secureUrlBuilder = new UriBuilder(currentUrl);
            secureUrlBuilder.Scheme = Uri.UriSchemeHttps;
            //use the default port.  
            secureUrlBuilder.Port = -1;
            //redirect and end the response. 
            System.Web.HttpContext.Current.Response.Redirect(secureUrlBuilder.Uri.ToString());
        }

        base.OnInit(e);
    }
}

Then for pages that require SSL inherit from this base class:

public class Login : SecurePage
{
    protected void Page_Load
        (
        object sender,
        EventArgs e )
    {
    }
}
