你可以prevent从关闭ASP.NET应用程序？ [英] Can you prevent your ASP.NET application from shutting down?
问题描述
我想我听说ASP.NET应用程序会同时在空闲（即没有观众）后关闭。
I think I heard that ASP.NET applications will shut down after a while of being idle (i.e. no visitors).
有没有办法来prevent的发生这种行为？我有一个运行在的global.asax.cs一些code Application_Start事件定时器，并希望确保它继续运行，即使没有游客击中的部位。
Is there a way to prevent this behavior from happening? I have a timer that runs some code from the global.asax.cs application_start event, and want to make sure that it continues to run, even when no visitors are hitting the site.
在此先感谢！
推荐答案
您可以做到这一点的一些方法。
You can do it a few ways.
- 如果您可以控制IIS，你可以更改应用程序池中的空闲超时，默认为20分钟。
- 如果你没有在IIS（共享或其他托管）的控制，你可以使用外部服务来ping网站。 MyWebKeepAlive 或 Pingdom的是这种不错的选择。
- If you have control over IIS, you can change the "Idle Timeout" within the application pool, by default it is 20 minutes.
- If you do NOT have control over IIS (Shared or other hosting), you can use an external service to ping the site. MyWebKeepAlive or Pingdom are good options for this.
如果您正在选择二，我强烈建议外部源，因为它是少来管理，如果你没有IIS来配置，你最有可能没有可用来添加一个ping服务器应用程序。
If you are under option two, I strongly recommend an external source, as it is less to manage, and if you don't have IIS available to configure, you most likely don't have the server available to add a ping application to.
另外，我不建议的东西，在过程中与Web应用程序坐镇，因为我已经发现，那些可能会导致问题，当应用程序确实需要回收...
In addition, I do not recommend something that sits in-process with the web application, as I have found that those can cause issues when the application really does need to recycle...
最后一个思想
如果你去修改IIS空闲超时的路线，我不建议设置的应用程序池的常规回收。由于许多Web应用程序都从一个周期性循环中受益，也是最常用的空闲超时是最大的正规回收的因素。
If you do go the route of modifying the IIS Idle timeout, I do recommend setting a regular recycle of the application pool. As many web applications do benefit from a periodic recycle, and most commonly the idle timeout is the biggest regular recycle factor.
