// Package xhandler provides a bridge between http.Handler and net/context.
|
|
//
|
|
// xhandler enforces net/context in your handlers without sacrificing
|
|
// compatibility with existing http.Handlers nor imposing a specific router.
|
|
//
|
|
// Thanks to net/context deadline management, xhandler is able to enforce
|
|
// a per request deadline and will cancel the context in when the client close
|
|
// the connection unexpectedly.
|
|
//
|
|
// You may create net/context aware middlewares pretty much the same way as
|
|
// you would with http.Handler.
