I managed to fix the problem by writing extension method for this.

    public static string GetNiceUrl(this Product product, Category category = null)
    {
        return (GetCurrentDomain() + CatalogLibrary.GetNiceUrlForProduct(product, category));
    }

    private static string GetCurrentDomain()
    {
        var domains = Domain.GetDomainsById(uQuery.GetCurrentNode().Id).OrderByDescending(d => d.Name.Length);
        foreach (var domain in domains)
        {
            if(HttpContext.Current.Request.Url.AbsoluteUri.ToLower().Contains(domain.Name.ToLower()))
            {
                return domain.Name;
            }
        }
        return string.Empty;
    }

Is there maybe a better way to handle this scenario?
