Re: [undertow-dev] Howto create/configure a custom SessionManager and SessionConfig implementation?

I'm not actually trying to reusue the SessionCookieConfigImpl. But in the SessionManager javadoc, it clearly states that: * As part of session creation the session manager MUST attempt to retrieve the {@link SessionCookieConfig} from * the {@link HttpServerExchange} and use it to set the session cookie. The frees up the session manager from * needing to know details of the cookie configuration. When invalidating a session the session manager MUST * also use this to clear the session cookie. So while I can create my own SessionManager that completely ignores the SessionConfig object, as per the SessionManager javadocs, the manager must attempt to retrieve the SessionConfig object from the exchange to set the session cookie. I am just trying to fulfill the SessionManager requirements. But there is missing documentation indicating how/where one can specify the SessionCookieConfig implementation that I want undertow to use. I would like undertow to use my own custom implementation.
