In this post, I discuss the problem of duplicate requests in typical HTTP APIs and how to solve it.

In this post I talk about some limitations of APIs developed in enterprises nowadays and in particular about the problem of getting updates via normal HTTP APIs and how it can be solved by applying the Observer pattern.
