preventing cross-site request forgery (csrf) attacks in asp.net web forms

Question

I have created an ASP.Net Web Forms application using Visual Studio 2013 and I am using .NET Framework 4.5. I want to make sure my site is secure from Cross-Site Request For

Answer 1

You could use below piece of code, which will check the request where it is coming from

if ((context.Request.UrlReferrer == null || context.Request.Url.Host != context.Request.UrlReferrer.Host)) 
    {
        context.Response.Redirect("~/error.aspx", false);
    }

It works great for me!!!
