nopCommerce on AppHarbor. Redirect loop-Collection of common programming errors

In addition to @TroelsThomsen fix, we use a wrapper in our base controller to ensure that all of our code is oblivious to appharbor port changing.

First, @TroelsThomsen fix in Webhelper.cs:75

public virtual string GetThisPageUrl(bool includeQueryString, bool useSsl)
        {
            string url = string.Empty;
            if (_httpContext == null)
                return url;

            if (includeQueryString)
            {
                string storeHost = GetStoreHost(useSsl);
                if (storeHost.EndsWith("/"))
                    storeHost = storeHost.Substring(0, storeHost.Length - 1);
                url = storeHost + _httpContext.Request.RawUrl;
            }
            else
            {
#if DEBUG
                var uri = _httpContext.Request.Url;

#else
                //Since appharbor changes port number due to multiple servers, we need to ensure port = 80 as in AppHarborRequesWrapper.cs
                var uri = new UriBuilder
                {
                    Scheme = _httpContext.Request.Url.Scheme,
                    Host = _httpContext.Request.Url.Host,
                    Port = 80,
                    Path = _httpContext.Request.Url.AbsolutePath,
                    Fragment = _httpContext.Request.Url.Fragment,
                    Query = _httpContext.Request.Url.Query.Replace("?", "")
                }.Uri;
#endif
                url = uri.GetLeftPart(UriPartial.Path);
            }
            url = url.ToLowerInvariant();
            return url;
        }

So what we did is simply add files from https://gist.github.com/1158264 into Nop.Core\AppHarbor

and modified base controllers:

• nopcommerce\Presentation\Nop.Web\Controllers\BaseNopController.cs

  public class BaseNopController : Controller
  {
      protected override void Initialize(RequestContext requestContext)
      {
          //Source: https://gist.github.com/1158264
          base.Initialize(new RequestContext(new AppHarborHttpContextWrapper(System.Web.HttpContext.Current),
                                             requestContext.RouteData));
      }
      //Same file from here downwards...
  }
  

• nopcommerce\Presentation\Nop.Web.Admin\Controllers\BaseNopController.cs

  public class BaseNopController : Controller
  {
  protected override void Initialize(System.Web.Routing.RequestContext requestContext)
  {
      //set work context to admin mode
      EngineContext.Current.Resolve().IsAdmin = true;
  
      //Source: https://gist.github.com/1158264
      base.Initialize(new RequestContext(new AppHarborHttpContextWrapper(System.Web.HttpContext.Current), requestContext.RouteData));
  
      //base.Initialize(requestContext);
  }
      //Same file from here downwards...
  }
