Functions

func Recoverer

func Recoverer(onError func(err error, w http.ResponseWriter, r *http.Request)) mux.Middleware

func XFrameOptions

func XFrameOptions(options XFrameOption) mux.Middleware

X-Frame-Options is a header that can be used to indicate whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object>.

Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

Types

type XFrameOption

type XFrameOption string

XFrameOption is the type for the XFrameOptions middleware.

const (
	// XFrameDeny is the most restrictive option, and it tells the browser to not display the content in an iframe.
	XFrameDeny XFrameOption = "DENY"
	// XFrameSame is the default value for XFrameOptions.
	XFrameSame XFrameOption = "SAMEORIGIN"
	// XFrameAllow is a special case, and it should not be used.
	// It is obsolete and is only here for backwards compatibility.
	XFrameAllow XFrameOption = "ALLOW-FROM"
)
