更新时锁定缓存？ [英] Lock cache while updating it?
问题描述
我使用System.Web.Caching在VB.NET中缓存一些数据，是否可以锁定缓存以便其他会话尝试访问同一缓存
等待更新？我有缓存使用滑动超时和
a依赖于从中提取数据的文本文件。
如果它是相关的，根据当前的统计数据，我做不要期望超过
大约400人同时访问该网站。
我看到它在C＃中看起来很容易但我不能找到关于VB的任何内容。

I am caching some data in VB.NET using System.Web.Caching, is it possible to
lock the cache so that other sessions attempting to access the same cache
wait when it is being updated? I have the cache using a sliding timeout and
a dependency on the text file its data is extracted from.
If it''s relevant, based on current statistics, I do not expect more than
about 400 people to be accessing the web site at the same time.
I''ve seen it appears easy in C# but I couldn''t find anything regarding VB.

推荐答案
Andrew，
你让我好奇，你为什么要那样做？在我看来，这是一个奇怪的解决方案，因为你应该为那些尝试在我的想法中访问缓存的其他399个人做出机制。什么时候，比什么呢？
抓住了什么？
我真的很好奇你是怎么做到的。

Andrew,
You make me curious, why would you do that? Seems to me a strange solution,
because you should than make a mechanisme for those other 399 who try to
access that cache in my idea. When it is, than what it the action on that
catch?
I am real curious about this how you did that.

缓存数据是一个查找表，每个用户都有相同的数据。
缓存适用于Web应用程序而不是每个会话。除非我
误解了文档。
Andrew
The cached data is a lookup table which has the same data for every user.
The cache applies to the web application rather than per-session. Unless I
have misunderstood the docs.

Andrew，
清除，
是不是更新表格，创建一个页面来杀死
缓存并让它去再次，我假设缓存是在什么时候创建的？
什么都没有？
我从来没有使用过那个缓存，但这是我从它的理解，
可能会首先尝试这样做。
Cor
Andrew,
Clear,
Is it than not something as updating the tables, create a page to kill the
cache and let it go again, where I assume that the cache is created when it
is nothing?
I never used that cache, however that is from what I understand from it,
would probably as first try to do it.
