Enabling HttpSession Support - Atmosphere/atmosphere GitHub Wiki
By default, the Atmosphere Framework doesn't create sessions and isn't using them. If your application uses HttpSession
, you need to tell Atmosphere to track the session as well by enabling it, in web.xml
/ application.xml
:
<listener>
<listener-class>org.atmosphere.cpr.SessionSupport</listener-class>
</listener>
...
<context-param>
<param-name>org.atmosphere.cpr.sessionSupport</param-name>
<param-value>true</param-value>
</context-param>
This is specially important if you are using WebSocket because of the difference of WebServer implementation, the framework will makes sure it works uniformly with all of them.
