ASIHTTPRequest足够了吗？

大家都知道ASIHTTPRequest系列的类很好用，功能很强大。但也像NSURLConnection一样，一个网络请求就需要实例化一个对象，而且无法避免重复请求的问题。
        我个人不习惯用ASIHTTPRequest，因为它功能太强大了，函数太多了，而我们平时的项目仅仅是处理基于HTTP协议的网络交互，用ASIHTTPRequest未免太“奢侈”了。更重要的是，它并无法避免网络的重复请求的问题，而且无法控制网络请求数量，所以仅仅使用ASIHTTPRequest还不够。
        事实上，用NSURLConnection足够了。下面是我写的封装
