Class IdCookieAccessor

java.lang.Object

services.publix.idcookie.IdCookieAccessor

@Singleton
public class IdCookieAccessor
extends java.lang.Object

This class offers a simple interface to extract, log and discard IdCookies.

Internally this class accesses JATOS' ID cookies in the HTTP Request or Response. It stores the extracted IdCookieModel in a IdCookieCollection. Additionally it puts the IdCookieCollection in the RequestScope for easier retrieval in subsequent calls within the same Request.

Each browser can run up to IdCookieCollection.MAX_ID_COOKIES ID studies at the same time. This means that there are the same number of ID cookies stored in the browser as studies are currently running (although part of them might be abandoned).
