## Class SessionHandler

- java.lang.Object
- - io.vertx.reactivex.ext.web.handler.SessionHandler

- All Implemented Interfaces:
    Handler<RoutingContext>

      public class SessionHandler
      extends Object
      implements Handler<RoutingContext>

  A handler that maintains a `Session` for each browser session.

  It looks up the session for each request based on a session cookie which contains a session ID. It stores the session when the response is ended in the session store.

  The session is available on the routing context with .

  The session handler requires a `CookieHandler` to be on the routing chain before it.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.

      Set the session cookie name
      Parameters:
        `sessionCookieName` - the session cookie name
