要查看HTTP报头如何工作，让我们构建、安装并运行一个HTTP反向代理来缓存一个小型PHP应用程序的输出。
To watch the HTTP headers in action, let's build, install, and run an HTTP reverse proxy to cache the output of a small PHP application.
缓存：反向代理服务器可以缓存静态内容以提供更好的性能。
Caching: The reverse proxy server can cache static content to provide better performance.
定义一种并不缓存从执行请求转发的 WebSeal反向代理服务器直接提供的任何数据的配置，这样就可以避免以上情况。
The scenario can be avoided by defining a configuration so that it will not cache anything served directly from a WebSeal reverse proxy server that performs redirects.
反向代理维护和服务的缓存可以分担Web应用程序的重担。
The cache that the reverse proxy maintains and serves can unburden your Web application.
在加速Web应用程序时，最有效、最常用的一种方法就是在 Web 应用程序之前放置一个缓存反向代理。
One of the most effective and frequently-used methods of speeding up a web application is to drop a caching reverse proxy in front of it.
例如，服务器端基础结构中的某种反向Web代理可能提供某些缓存功能。
An example would be some sort of reverse Web proxy in the server side infrastructure, perhaps providing some caching functionality.
除了迅速交付之外，反向代理缓存模式还提供了许多其他优点，包括。
In addition to expediting delivery, the reverse-proxy caching scheme provides many other benefits, including.
反向和转发代理服务器通常在门户服务器环境中作为此类缓存使用。
Reverse and forward proxy servers typically act as these Shared caches in a portal server environment.
门户将自动确定哪些聚合页面可以缓存，并自动设置页面标头以将站点中的静态部分缓存到反向代理或浏览器中。
The portal automatically determines which aggregated pages can be cached and sets page headers that enable static parts of your site to be projected into caches in reverse proxies or browsers.
因此，页面可以在可能的最长时间内在反向代理和浏览器缓存中进行缓存。
As a result, the page can be cached in reverse proxies and browser caches with the maximum time possible.
在这里，我将把PHP与名为反向代理(reverse proxy)的智能软件结合使用来缓存页面和节省服务器。
Here, I combine PHP with smart software called a reverse proxy to cache pages and save servers.
