摘要： The apparent speed of a connection between a browser at a user station and a proxy or gateway on a network such as the Internet is increased by providing a local proxy at the user station which interacts with a remote proxy. While the remote proxy is retrieving a newly requested World Wide Web page, for example, from the appropriate content provider, it may also be sending to the local proxy a stale cached version of that page. When the new version of the page is finally retrieved, the remote proxy determines the differences between the new version and the stale version, and, assuming the differences do not exceed the new page in size, sends the differences to the local proxy which then reconstructs the new page from the differences and the stale version. The local proxy delivers the new page to the browser, which need not even be aware that a local proxy exists; it is aware only that it received the page it requested. Because computational speed and power are frequently higher and cheaper than transmission speed, the apparent speed of the connection between the user station and the network has been increased at modest cost.

摘要翻译：通过在与远程代理进行交互的用户站处提供本地代理来增加用户站上的浏览器与诸如因特网的网络上的代理或网关之间的连接的速度。虽然远程代理正在检索新请求的万维网页面，例如，从适当的内容提供商，它也可能会向本地代理发送该页面的陈旧的缓存版本。当最终检索到新版本的页面时，远程代理确定新版本和旧版本之间的差异，并且假设差异不超过新页面大小，将差异发送到本地代理，然后重新构建新页面的差异和陈旧的版本。本地代理将新页面传递到浏览器，甚至不需要知道本地代理存在; 它只知道它收到了它要求的页面。由于计算速度和功率通常比传输速度更高和便宜，所以用户站和网络之间的连接的速度已经以适度的成本增加了。
