是什么原因导致在IIS应用程序池回收？ [英] What causes an application pool in IIS to recycle?

问题描述

我一直在寻找这个信息无济于事。为什么我需要这个的背景是<一个href=\"http://stackoverflow.com/questions/271944/storing-temporary-user-files-in-aspnet-in-medium-trust\">another问题我问这里。更具体地说，它创建/更新/的App_Data中删除文件会导致池回收？

I have been searching for info on this to no avail. The context of why i need this is another question I asked here. More specifically, does creating/updating/deleting files in App_Data cause a pool recycle?

如果有人可以提供什么原因导致回收的详细列表，这将是巨大的。

If someone could provide a detailed list of what causes a recycle, that would be great.

更新：作为两个用户已经发现我也很乐意回答指定的，而不是只回收的AppDomain整个游泳池的原因。

UPDATE: As two users already noticed I would also be happy to an answer specifying reasons for recycling the AppDomain only and not the whole pool.

推荐答案

两种不同的效果 - 在程序池进程是潜在的多个AppDomain的主机。通常，这可以通过许多的效果例如可以回收时间 - 每一个N个小时，缺乏的请求，内存使用等配置在IIS配置管理器

Two different effects - the AppPool process is the host for potentially multiple appdomains. Typically this can be recycled by a number of effects e.g. time - every 'n' hours, lack of requests, memory use etc. Configured in IIS Config Manager.

AppDomain中 - 您的应用程序根目录的托管实例，可以更频繁地循环而不影响程序池的AppDomain其他。苔丝对AppDomain的回收职位是pretty见地

AppDomain - the hosted instance of your application root, can be cycled more frequently without affecting other AppDomains in the AppPool. Tess' post on AppDomain recycling is pretty insightful

You are writing to a folder monitored for recompilation - this will trigger the appdomain recreation at some point.
