Implement the Awesomium.Core.IResourceInterceptor interface and attach it to your webcore session with WebCore.ResourceInterceptor = new ResourceInterceptor();

Here is a simple ResourceInterceptor in C#.

using System;
using System.IO;
using System.Reflection;
using Awesomium.Core;

namespace MyApp
{
    public class ResourceInterceptor : IResourceInterceptor
    {
        /// <summary>
        ///     Not used.
        /// </summary>
        public virtual ResourceResponse OnRequest(ResourceRequest request)
        {
             return null;
        }

        /// <summary>
        ///     Optionally blocks any web browser requests by returning true when the URL contains "/view/".
        /// </summary>
        public virtual bool OnFilterNavigation(NavigationRequest request)
        {
            return String.Contains(request.Url.AbsolutePath, "/ViewPdf/", StringComparison.InvariantCultureIgnoreCase);
        }
    }
}
