Last week my friend and colleague Greg Coffman had asked me if I knew of a way to restrict IP access to directories within the Sitecore web application, and I recalled reading a post by Alex Shyba quite some time ago.

Although Alex’s solution is probably good enough in most circumstances, I decided to explore other solutions, and came up with the following <httpRequestBegin> pipeline processor as another way to accomplish this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Hosting;

using Sitecore.Configuration;
using Sitecore.Diagnostics;
using Sitecore.Pipelines.HttpRequest;
using Sitecore.Web;

namespace Sitecore.Sandbox.Pipelines.HttpRequest
    public class FilePathRestrictor : HttpRequestProcessor 
        public override void Process(HttpRequestArgs args)
            Assert.ArgumentNotNull(args, "args");
            if (!ShouldRedirect(args))


        private bool ShouldRedirect(HttpRequestArgs args)
            return CanProcess(args, GetFilePath(args)) 
                    && !CanAccess(args.Context.Request.UserHostAddress);

        protected virtual string GetFilePath(HttpRequestArgs args)
            if (string.IsNullOrWhiteSpace(Context.Page.FilePath))
                return args.Url.FilePath;

            return Context.Page.FilePath;

        protected virtual bool CanProcess(HttpRequestArgs args, string filePath)
            return !string.IsNullOrWhiteSpace(filePath)
                    && !string.IsNullOrWhiteSpace(RootFilePath)
                    && AllowedIPs != null
                    && AllowedIPs.Any()
                    && (HostingEnvironment.VirtualPathProvider.DirectoryExists(filePath)
                        || HostingEnvironment.VirtualPathProvider.FileExists(filePath))
                    && args.Url.FilePath.StartsWith(RootFilePath, StringComparison.CurrentCultureIgnoreCase)
                    && !string.IsNullOrWhiteSpace(args.Context.Request.UserHostAddress)
                    && !string.Equals(filePath, Settings.NoAccessUrl, StringComparison.CurrentCultureIgnoreCase);

        protected virtual bool CanAccess(string ip)
            Assert.ArgumentNotNullOrEmpty(ip, "ip");
            return AllowedIPs.Contains(ip);

        protected virtual void RedirectToNoAccessUrl()

        protected virtual void AddAllowedIP(string ip)
            if (string.IsNullOrWhiteSpace(ip) || AllowedIPs.Contains(ip))


        private string RootFilePath { get; set; }

        private IList<string> _AllowedIPs;
        private IList<string> AllowedIPs 
                if (_AllowedIPs == null)
                    _AllowedIPs = new List<string>();

                return _AllowedIPs;

The pipeline processor above determines whether the IP making the request has access to the directory or file on the file system — a list of IP addresses that should have access are passed to the pipeline processor via a configuration file, and the code does check to see if the requested URL is a directory or a file on the file system — by matching the beginning of the URL with a configuration defined root path.

If the user does not have access to the requested path, s/he is redirected to the “No Access Url” which is specified in the Sitecore instance’s configuration.

The list of IP addresses that should have access to the directory — including everything within it — and the root path are handed to the pipeline processor via the following patch configuration file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
        <processor patch:before=" processor[@type='Sitecore.Pipelines.HttpRequest.FileResolver, Sitecore.Kernel']"
                   type="Sitecore.Sandbox.Pipelines.HttpRequest.FilePathRestrictor, Sitecore.Sandbox">
          <AllowedIPs hint="list:AddAllowedIP">

Since my IP is, I decided to only allow access to my Sitecore directory — this also includes everything within it — in the above configuration file for testing.

After navigating to /sitecore of my local sandbox instance, I was redirected to the “No Access Url” page defined in my Web.config:
