Where does the word idempotency come from?

“幂等性”一词源自何处？

And just taking one of those things, idempotency, and realizing it's hard to achieve on your own throughout, especially more complicated applications.

其中一项——幂等性为例，认识到在整个过程中，尤其是在更复杂的应用程序中，自己实现它是相当困难的。

I mean, you could just limit to one request per day, but if you're not going to do that, how do people usually implement or ensure idempotency in their applications?

我的意思是， 简单限制允许一个请求，但如果不打算这么做，人们通常是如何在应用程序中实现或确保幂等性的呢？

Mobile App Test Case Design Mobile app test case design includes but is not limited to: Functional Testing: Covers UI, functional scenarios, business logic, concurrency, idempotency, and duplicate request handling.

移动应用测试用例设计 移动应用测试用例设计包括但不限于: 功能测试: 涵盖 UI、功能场景、业务逻辑、并发性、临时性和重复请求处理。

The HTTP standard has actually a new, has defined a header where you can put an idempotency key and the servers, when they support this, are supposed to understand if that key is set.

HTTP标准实际上有了新的规定，定义了一个放置幂等性键的头部，当服务器支持这一规定时， 应该能够识别这个键是否被设置。
