如果出现未将对象引用设置到对象的实例的异常 请修改       问题解决~

 

            try
            {
                context.RewritePath(sendToUrlLessQString, String.Empty, queryString);

            }
            catch
            {
                context.RewritePath(sendToUrlLessQString+"?"+queryString);
            }

 

因为把请球直接交给asp.net处理，IIS定义的默认首页将会失效，出现这种情形单独为首页配置一下 解决问题
