当前绝大多数互联网流量是由Web浏览应用程序产生的。代理缓存允许将一些最流行的Web对象缓存在网络中的中间节点，已被证明可以提供实质性的性能改进。在本文中，我们认为，图像特定的缓存策略是可取的，并会导致提高性能的方法对待所有对象一样。我们建议，软缓存，其中一个图像可以被缓存在一组级别的分辨率，可以受益于整体性能时，结合缓存管理策略，估计，为每个对象，带宽的服务器存储的对象和适当的分辨率水平所需的用户。我们正式的该高速缓存管理问题在这些条件下，并描述了一个实验系统来测试这些技术。
The vast majority of current Internet traffic is generated by web browsing applications. Proxy caching, which allows some of the most popular web objects to be cached at intermediate nodes within the network, has been shown to provide substantial performance improvements. In this paper we argue that image-specific caching strategies are desirable and will result in improved performance over approaches treating all objects alike. We propose that Soft Caching, where an image can be cached at one of a set of levels of resolutions, can benefit the overall performance when combined with cache management strategies that estimate, for each object, both the bandwidth to the server where the object is stored and the appropriate resolution level demanded by the user. We formalize the cache management problem under these conditions and describe an experimental system to test these techniques.
