设置了http缓存表题头之后，可以在这些网络资源上对文档进行缓存，客户端请求也可在不必返回原始服务器的情况下得以满足。
When HTTP cache headers are set, the documents can be cached on these network resources, and client requests can be satisfied without having to go back to the origin server.
第一，缓存帮助减少服务器上的资源开销。
服务器资源问题可以这样解决：将以前的数据缓存，然后将最新添加的数据集成进来。
The server resource issue can be addressed by caching prior data and then aggregating the very newest additions.
如果曾用于生成特定页面的标记的某个门户资源的服务器端状态发生更改，需要重新生成此页面，因而缓存的视图会变为无效。
If the server side state of a portal resource that was once required to generate the markup for a specific page changes, this page needs to be regenerated, and thus the cached view becomes invalid.
注意，如果变量设置太大，LotusQuickr服务器需要消费更多资源才能处理更大的缓存大小。
Note that if this variable is set too large, the Lotus Quickr server spends more resources to handle the larger cache size.
图4显示了Feed生成器、资源集合和潜在Web服务器或代理缓存间的关系。
Figure 4 illustrates the relationship between the feed producer, the resource collection, and a potential web server or proxy cache.
因此，Web浏览器或代理服务器无法缓存服务器资源。
As a consequence, a Web browser or proxy servers can't cache server resources.
此外，可以将静态资源组件如图像、附件和CSS文件缓存在Edge (Web服务器)级。
In addition, the static resource components such as images, attachments, and CSS files can be cached at the Edge (Web server) level.
这时，资源适配器将执行一个有序的关闭(例如，释放网络和应用服务器资源，并将所有缓存的数据强行送回后端)。
At this point, the resource adapter should perform an orderly shutdown (for example, releasing network and application-server resources and forcing any cached data to the back end).
现在，在浏览器级和应用服务器级都会缓存表单资源，这样多个用户都可以快速访问表单资源。
Form resources are now cached at both the browser level and the application server level so that multiple users can quickly access the form resources.
因为边缘服务器缓存的资源要在下一次请求时返回，一定要确保缓存的数据表示资源的正确内容。
Since a resource cached by the edge server is returned in the next request, it is very important to make sure the cached data represents the correct content of that resource.
对于HTTP缓存，在出现可能修改资源的服务器端状态的资源交互时，缓存项将失效。
In the case of HTTP caching, the cache entries are invalidated in case an interaction with the resource occurs that potentially modifies the server side state of the resource.
缓存服务器通过在数据库中存储处理过的资源解决了这个问题。
Cache Server solves that issue by storing processed assets in the persistent database for later use.
缓存(瓦片)地图资源已经利用了有地图服务器的定义的瓦片计划。
Cached (tiled) map resources always utilize the tiling scheme defined by the map service host.
为了提高视频服务器的资源利用率、提高客户端节目的播放质量和流畅性，我们提出一种动态的缓存管理算法。
In order to improve the efficiency of the resource utilization of the VOD server and for the high quality of playback in the clients, we propose a novel dynamic buffer management algorithm.
利用有效的缓存机制，可以避免到数据库的网络往返时间，绕过占用很多资源的计算，并节省服务器资源，同时改善响应时间和等待时间。
Effective cache mechanism can avoid round trip time to database, avoid calculations which occupying much time, save server resource, as well as improving the response time and waiting time.
在移动主机中对查询数据进行语义缓存，将提高移动主机对服务器资源的利用效率以及可用性。
The resource of servers always is visited by mobile computer. Therefore, the efficiency and availability will be improved when querying data from semantic cache in mobile computer.
同时，让边缘缓存服务器与邻近用户自发组建P 2 P下载网络，将资源更加边缘化，通过就近获取资源，提高下栽速度。
Meanwhile, edge cache server and its users nearby automatically construct P2P download network. So resources becoming more marginate and then users obtain the high download speed.
