sessions

gorilla/sessions provides cookie and filesystem sessions and infrastructure for
custom session backends.

The key features are:

• Simple API: use it as an easy way to set signed (and optionally
  encrypted) cookies.
• Built-in backends to store sessions in cookies or the filesystem.
• Flash messages: session values that last until read.
• Convenient way to switch session persistency (aka "remember me") and set
  other attributes.
• Mechanism to rotate authentication and encryption keys.
• Multiple sessions per request, even using different backends.
• Interfaces and infrastructure for custom session backends: sessions from
  different stores can be retrieved and batch-saved using a common API.

Let's start with an example that shows the sessions API in a nutshell:

	import (
		"net/http"
		"github.com/gorilla/sessions"
	)

	var store = sessions.NewCookieStore([]byte("something-very-secret"))

	func MyHandler(w http.ResponseWriter, r *http.Request) {
		// Get a session. We're ignoring the error resulted from decoding an
		// existing session: Get() always returns a session, even if empty.
		session, _ := store.Get(r, "session-name")
		// Set some session values.
		session.Values["foo"] = "bar"
		session.Values[42] = 43
		// Save it before we write to the response/return from the handler.
		session.Save(r, w)
	}

First we initialize a session store calling NewCookieStore() and passing a
secret key used to authenticate the session. Inside the handler, we call
store.Get() to retrieve an existing session or a new one. Then we set some
session values in session.Values, which is a map[interface{}]interface{}.
And finally we call session.Save() to save the session in the response.

Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
with
context.ClearHandler
as or else you will leak memory! An easy way to do this is to wrap the top-level
mux when calling http.ListenAndServe:

More examples are available on the Gorilla
website.
