Unfortunately everything I've seen so far has a high chance of +breaking your application. + +The main problem is that a `http.ResponseWriter` often implements additional +interfaces such as `http.Flusher`, `http.CloseNotifier`, `http.Hijacker`, `http.Pusher`, and +`io.ReaderFrom`. So the naive approach of just wrapping `http.ResponseWriter` +in your own struct that also implements the `http.ResponseWriter` interface +will hide the additional interfaces mentioned above. This has a high change of +introducing subtle bugs into any non-trivial application. + +Another approach I've seen people take is to return a struct that implements +all of the interfaces above. However, that's also problematic, because it's +difficult to fake some of these interfaces behaviors when the underlying +`http.ResponseWriter` doesn't have an implementation. It's also dangerous, +because an application may choose to operate differently, merely because it +detects the presence of these additional interfaces. + +This package solves this problem by checking which additional interfaces a +`http.ResponseWriter` implements, returning a wrapped version implementing the +exact same set of interfaces. + +Additionally this package properly handles edge cases such as `WriteHeader` not +being called, or called more than once, as well as concurrent calls to +`http.ResponseWriter` methods, and even calls happening after the wrapped +`ServeHTTP` has already returned. + +Unfortunately this package is not perfect either. It's possible that it is +still missing some interfaces provided by the go core (let me know if you find +one), and it won't work for applications adding their own interfaces into the +mix. + +However, hopefully the explanation above has sufficiently scared you of rolling +your own solution to this problem. httpsnoop may still break your application, +but at least it tries to avoid it as much as possible. + +Anyway, the real problem here is that smuggling additional interfaces inside +`http.ResponseWriter` is a problematic design choice, but it probably goes as +deep as the Go language specification itself. But that's okay, I still prefer +Go over the alternatives ;). + +## Performance + +``` +BenchmarkBaseline-8 20000 94912 ns/op +BenchmarkCaptureMetrics-8 20000 95461 ns/op +``` + +As you can see, using `CaptureMetrics` on a vanilla http.Handler introduces an +overhead of ~500 ns per http request on my machine.
