在AppHarbor上模拟后台任务
我正在使用 System.Runtime.Caching.MemoryCache 来模拟部署在 AppHarbor 上的正在运行的 .NET MVC 应用程序上的重复任务。
缓存中的条目是使用 CacheItemPolicy 添加的，该策略包含 AbsoluteExpiration 偏移量和调用方法并重新触发在缓存中添加项目的RemovedCallback（如此处）
MemoryCache 在 Application_Start 中首次填充。它在本地运行良好，但部署在 AppHarbor 上后似乎不起作用（也尝试使用 HttpRuntime.Cache，结果相同）。
我的应用程序在 AppHarbor 上的 CANOE（免费）帐户下运行，该帐户只有一名工作人员。这是否意味着在升级到某些付费计划之前我将无法模拟后台任务？
谢谢！
I'm using System.Runtime.Caching.MemoryCache to simulate a repeated task on a running .NET MVC application deployed on AppHarbor.
Entries in the cache are added using a CacheItemPolicy which contains an AbsoluteExpiration offset and a RemovedCallback that calls a method and retriggers the adding of the item in the cache (as described here)
MemoryCache is populated first time in Application_Start. It works fine locally, but doesn't seem to work once deployed on AppHarbor (tried also with HttpRuntime.Cache, same result).
My application is running under a CANOE (free) account on AppHarbor that only has one worker. Does this mean that I won't be able to simulate the background task until I upgrade to some paid plan?
Thanks!

您的应用程序必须时不时地有访问者才能发挥作用。除了 StillAlive 之外，Pingdom 也是向应用程序生成请求的不错选择。您还应该看看 MomentApp。我们预计后台任务很快就会准备就绪。
Your application has to have visitors every once in a while for this to work. Other than StillAlive, Pingdom is also a good bet for generating requests to your app. You should also take a look at MomentApp. We expect to have background tasks ready shortly.
我不认为升级会有帮助，他们正在努力向 AppHarbor 添加后台作业，但据我所知，它们还可用。
使用 https://stillalive.com/ 之类的服务定期访问您网站上的页面然后旋转怎么样？一个新线程并开始运行你的后台任务？它作为免费附加组件提供。
我正在考虑在等待后台任务功能可用时做这样的事情。
I don't think upgrading will help, they are working on adding background jobs to AppHarbor but to my knowledge they available yet.
What about using a service like https://stillalive.com/ to periodically hit a page on your site that then spins up a new thread and starts running your background task? Its available as a free add-on.
I was thinking of doing something like this while waiting for the background task functionality to be available.
