In chapter 6, we introduced some basic concepts pertaining to sessions in Go, and we implemented a sessions manager. The Beego framework uses this session manager to implement some convenient session handling functionality.
## Session integration
beego mainly in the following global variables to control the session handling:
## Integrating sessions
Beego handles sessions mainly according to the following global variables:
// related to session
SessionOn bool // whether to open the session module, the default is not open
SessionProvider string // session backend processing module provided, the default is sessionManager supported memory
SessionName string // client name saved in cookies
SessionGCMaxLifetime int64 // cookies validity
SessionOn bool // whether or not to open the session module. Defaults to false.
SessionProvider string // the desired session backend processing module. Defaults to an in-memory sessionManager
SessionName string // the name of the client saved cookies
SessionGCMaxLifetime int64 // cookie validity
GlobalSessions *session.Manager// global session controller
Of course, the above values of these variables need to be initialized, you can also follow the code to match the configuration file to set these values:

Add the following code in the `beego.Run` function:
if SessionOn {
GlobalSessions, _ = session.NewManager(SessionProvider, SessionName, SessionGCMaxLifetime)
go GlobalSessions.GC()
}
So long SessionOn set to true, then it will open the session by default function to open an independent goroutine to handle session.
As long as `SessionOn` is set to true, it will open the session by default with an independent goroutine session handler
In order to facilitate our custom Controller quickly using session, the author `beego.Controller` provides the following methods:
To assist us in quickly using sessions in a custom Controller, `beego.Controller` provides the following method:
func (c *Controller) StartSession() (sess session.Session) {
sess = GlobalSessions.SessionStart(c.Ctx.ResponseWriter, c.Ctx.Request)
