cometd - Storing User Credientials in the Bayeux Server -

i'd store clients username , sessionid when client subscribes particular channel. when override canhandshake() can user credentials using following:

username = (string) authentication.get("username"); sessionid = (string) authentication.get("sessionid"); 

just wondering how can store these credentials , later retrieve them? i've had @ authentication documentation here , mentions linking authentication data session. bayeux server side session??

thanks

the "linking" can done in several ways.

you can link information in external map via:

@override public boolean canhandshake(bayeuxserver server, serversession session, servermessage message) {     ...     map<string, object> authentication = ...;     map.put((string)authentication.get("username"), session);     ... } 

where map can java.util.concurrenthashmap<string, serversession> field in security policy itself, or in object such user service.

for simpler use cases, username can linked directly session in way:

session.setattribute("username", authentication.get("username")); 

or can use both techniques.
