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

Wed Mar 29 09:01:06 EDT 2017

Agreed, but I want to use my own SessionConfig implementation in which the
Sessionid is stored in a different cookie structure then the default
implementation.

I was looking for something that allows me to specify the SessionConfig
implementation I want undertow to use, but can't find that config option
anywhere.

Thanks,

Eric

A SessionConfig is just an interface for the SessionManager to retrieve the
session ID.
You do want to store session IDs in cookies, is that correct?
In that case, simply use the default SessionCookieConfig:

src/main/java/io/undertow/server/session/SessionCookieConfig.java

Cheers,
Antoine
