Hi, 

WE have a custom url rewriter that inherits from the FriendlyUrlRewriter and this does not work with 7.5 any longer. We have tried changing the functionality to inherit from the hierarchicalUrlRewriterProvider, but this is missing a function: ConvertToInternalInternal. 

My question is how do I recreate this functionality? The functionality is basically as follows : 

protected override bool ConvertToInternalInternal(UrlBuilder url, ref object internalObject)
        {
            bool urlRewritten = false;
            KeyValuePair qsAdditional = new KeyValuePair();

            if (url != null)
            {
                PageReference pageRef = null;

                if (!url.Path.ToLower().StartsWith("/events/"))  // Don't try to resolve a link that starts with 'events' as this has already been rewritten
                {
                    pageRef = TryResolveEventsUrl(url);

                    if (PageReference.IsNullOrEmpty(pageRef))
                    {
                        pageRef = TryResolveBusinessLineClaimsUrl(url, out qsAdditional);
                    }

                    if (!PageReference.IsNullOrEmpty(pageRef))
                    {
                        // Rewrite the url based on the page ref
                        url.Path = new Url(DataFactory.Instance.GetPage(pageRef).StaticLinkURL).Path;

                        // Add the page id back to the querystring
                        url.QueryCollection.Add("id", pageRef.ID.ToString());

                        // Add additional querystring parameters to the internal url
                        url.QueryCollection.Add("epslanguage", ContentLanguage.PreferredCulture.TwoLetterISOLanguageName);

                        // Add any additional querystring parameters
                        if (!String.IsNullOrEmpty(qsAdditional.Key))
                        {
                            url.QueryCollection.Add(qsAdditional.Key, qsAdditional.Value);
                        }

                        urlRewritten = true;
                    }
                }
            }

            if (urlRewritten)
            {
                return true;
            }
            else //Not a custom url so use default rewriting behaviour
            {
                return base.ConvertToInternalInternal(url, ref internalObject);
            }

        }

Thank you!
