trait FlashMapSupport extends Handler with ServletContextAccessor with SkinnyMicroContextInitializer with UnstableAccessValidationConfig with ServletApiImplicits with SessionImplicits

Allows an action to set key-value pairs in a transient state that is accessible only to the next action and is expired immediately after that. This is especially useful when using the POST-REDIRECT-GET pattern to trace the result of an operation.

post("/article/create") {
  // create session
  flash("notice") = "article created succesfully"
  redirect("/home")
}
get("/home") {
  // this will access the value set in previous action
  stuff_with(flash("notice"))
}
