trait FlashMapSupport extends Handler
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 successfully" redirect("/home") } get("/home") { // this will access the value set in previous action stuff_with(flash("notice")) }
