After a bit of research, I decided to use WCF in my application to do inter process communication, so I am using the NetNamedPipeBinding binding. The ServiceHost hosting application is not a dedicated server, so it has to spawn the ServiceHost via a thread. So far so good. So I have something like the following: Foo() { Thread serverThread = new Thread(new ThreadStart(ServerThread)); serverThread.Start(); Console.WriteLine("Foo Exited"); } ServerThread() { Uri baseAddress = new Uri("net

Thanks. 回答1: from the Sun Tutorials Note: If the JVM exits while the try or catch code is being executed, then the finally block may not execute. Likewise, if the thread executing the try or catch code is interrupted or killed, the finally block may not execute even though the application as a whole continues. I don't know of any other ways the finally block wouldn't execute... 回答2: System.exit shuts down the Virtual Machine. Terminates the currently running Java Virtual Machine.

This includes an HTTP handler for urllib2 that supports HTTP 1.1 and keepalive: >>> import urllib2 >>> from urlgrabber.keepalive import HTTPHandler >>> keepalive_handler = HTTPHandler() >>> opener = urllib2.build_opener(keepalive_handler) >>> urllib2.install_opener(opener) >>> >>> fo = urllib2.urlopen('http://www.python.org') Note: you should use urlgrabber version 3.9.0 or earlier, as the keepalive module has been removed in version 3.9.1

When debugging, we noticed that when Fiddler is active, the requests are much faster - ~100ms per request. Some searches later we understood that was because Fiddler was using Keep-Alive connections when proxying calls, which makes our proxied calls much faster. We double-checked this in two ways. We set UseProxy to false and observed that the request went back to being slow. We turned off Fiddler's

每次当点击城市页面的按钮跳转到首页都会请求一次数据，这就造成了性能低， app.vue keep-alive 2、每次点击城市取对应的数据渲染到首页 keep-alive 解决： keep-alive vue activated 这个函数在每次跳转页面的时候会执行。 原文：https://www.cnblogs.com/warbj/p/9245037.html

搬运自： https://www.cnblogs.com/goloving/p/9256212.html 使用 <keep-alive> 会将数据保留在内存中，如果要在每次进入页面的时候获取最新的数据，需要在 activated 阶段获取数据，承担原来created钩子中获取数据的任务。 <keep-alive> activated deactivated activated：在组件被激活时调用， 在组件第一次渲染时也会被调用 ，之后每次keep-alive激活时被调用。 deactivated：在组件被停用时调用。 keep-alive 2.1.0 exclude keep-alive 什么时候获取数据？ 当引入 keep-alive keep-alive 所以，有需要的话，应该activated中留一份数据获取的代码，或者不要created部分，直接将created中的代码转移到activated中。 来源：博客园 作者： 林景之 链接：https://www.cnblogs.com/linjiangxian/p/11683889.html
