var ParseTime = func(text string) (t time.Time, err error) {
	t, err = time.Parse(http.TimeFormat, text)
	if err != nil {
		return http.ParseTime(text)
	}

	return
}

ParseTime parses a time header (such as the Date: header), trying each forth formats that are allowed by HTTP/1.1: time.RFC850, and time.ANSIC.

Functions

func IsZeroTime 

func IsZeroTime(t time.Time) bool

IsZeroTime reports whether t is obviously unspecified (either zero or Unix()=0).

Types

type App 

type App struct {
	Requests    []Path
	Handlers    HandlerMap
	Middlewares Handlers
	Prefix      string

	Routers RouterMap
	// contains filtered or unexported fields
}

App is the key struct of the package. App as a member of plugin entity contains the request and the corresponding handler. Prefix is the url prefix and MiddlewareList is for control flow.
