A remote shared cache typically does not provide any security mechanisms by default 遠(yuǎn)程共享緩存通常不提供任何缺省安全機制。
Reverse and forward proxy servers typically act as these shared caches in a portal server environment 反向和轉(zhuǎn)發(fā)代理服務(wù)器通常在門戶服務(wù)器環(huán)境中作為此類緩存使用。
Dynacache provides a powerful high performance distributed shared cache for websphere application server applications Dynacache為websphere application server應(yīng)用程序提供了強大的高性能分布式共享緩存。
With a field name , the directive applies only to the named field ; the rest of the response may be supplied from a shared cache 如果有字段名,則指令僅應(yīng)用于命名字段;響應(yīng)的其余部分可能由共享緩存提供。
Cache scope - indicates whether a response from websphere portal that is , a completely rendered page is cacheable in a shared or non - shared cache 指示來自websphere portal的響應(yīng)(即一個完全呈現(xiàn)的頁面)是否在共享緩存或非共享緩存中可緩存。
A shared map will try to keep the content of map instances on different nodes on a cluster in sync , whereas non - shared caches contain node - specific data 共享映射將試圖同步保留群集中不同節(jié)點的映射實例的內(nèi)容,而非共享緩存則包含特定于節(jié)點的數(shù)據(jù)。
If the cache may be shared , the portlet can use the pre - defined jndi name " services cache distributedmap " to access the globally shared cache 如果緩存可以共享, portlet可以使用預(yù)定義的jndi名稱“ services / cache / distributedmap ”訪問全局共享的緩存。
Without compromising its effectiveness in a wide variety of common - use cases , such as shared caches . table 1 gives a rough idea of the scalability differences between 高得多的可伸縮性,而且,對于很多類型的公用案例(比如共享的cache )來說,還不用損失其效率。
If fully rendered pages are stored in shared caches , there is the possibility that users who do not have access permissions to that page could still guess the url of such a page and load its contents from the cache 如果完全呈現(xiàn)的頁面存儲在共享緩存中,則那些不具有該頁面訪問權(quán)限的用戶仍然可能猜測出此類頁面的url ,從而從緩存中加載其內(nèi)容。
In cases where this set of circumstances is really a concern , this setting must be set to false to ensure that such sensitive pages are never cached in a remote shared cache , making sure that access to information contained on such pages cannot be obtained by guessing urls 如果真的需要考慮這樣的環(huán)境,必須將此設(shè)置為false ,以保證不會在遠(yuǎn)程共享緩存中對此類敏感頁面進行緩存,從而確保無法通過猜測url訪問此類頁面包含的信息。
