Hot to block access to page with defined URL in ASP.NET site on IIS except from one defined IP?

We have ASP.NET web site hosted on IIS. We need to block access to page "http://www.example.com/sample/page1.aspx" from any IP. We want to define single IP which can access this page.

What option of IIS or Windows can h开发者_如何学Celp me?

If you are using IIS7 + you could use the URL Rewrite Module http://www.iis.net/download/urlrewrite

However if you are using IIS6 you can try a tool like Helicon ISAPI Rewrite http://www.helicontech.com/isapi_rewrite/ which will allow you to write an IP based rule.

Try this in your code behind (although this is not IIS or Windows as you request):

if (Request.UserHostAddress == "1.1.1.1") {  }

Obviously substitute the IP address you want!
