Functions

func CookieRemoveRedirect

func CookieRemoveRedirect(c *gin.Context)

CookieRemoveRedirect deletes this application's authentication cookie and redirects to index page.

func NotAuthorized

func NotAuthorized() gin.HandlerFunc

NotAuthorized ensures that only clients with no 'Protokollamt' cookie present continue to the index page again. This allows to directly redirect to restricted pages if a correctly named cookie is found. Its validity is checked on a restricted page.
