Du kan f.eks. gøre det med et HTTP module...
1) Put noget i denne stil i din Web.Config:
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
<httpModules>
<add type="SiteBlocker.SiteBlockerClass, SiteBlocker" name="SiteBlockerClass"/>
</httpModules>
</system.web>
</configuration>
2) Derefter laver du en DLL som du uploader til bin-folderen på dit site.
Koden for denne DLL kunne være noget i stil med:
using System;
using System.Collections.Specialized;
using System.IO;
using System.Web;
using System.Web.Caching;

namespace SiteBlocker
{
public class SiteBlockerClass: IHttpModule
{
public SiteBlockerClass() { }
#region IHttpModule Members
public void Dispose() { }
public void Init(HttpApplication ctx)
{
ctx.BeginRequest += new EventHandler(this.ctx_BeginRequest);
}
#endregion
void ctx_BeginRequest(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;
if (app != null)
{
string ip = app.Context.Request.ServerVariables["REMOTE_ADDR"];
if (ip != null && ip == " ... din IP her ... ")
return;
app.Context.Response.StatusCode = 404;
app.Context.Response.SuppressContent = true;
app.Context.Response.End();
}
}
}
}
