// This example demonstrates a pluggable middleware approach to
// recovering from panics in HTTP handlers and sending HTTP 500
// responses to the client when panics happen.
//
// The middleware allows to use in any handlers without them
// being aware of anything special.
//
// Utilises middleware concepts, see:
//  - https://github.com/justinas/alice
//  - https://www.alexedwards.net/blog/making-and-using-middleware

// This example demonstrates how panics in handlers can be recovered,
// and HTTP 500 responses sent to the client when panic happens.
//
// Since the built-in http.ResponseWriter cannot be reset, any panic
// can lead to half-arsed responses in the buffer or worse.
// Also, since our panic handler needs to completely replace the response,
// we need our own fully buffered ResponseWriter.
//
// This demo implements such a buffered response writer as HttpBuffer.
