Hello Shiro users,

I am designing a stateless web application (no cookie at all), and have to use 
Subject.runAs() because subject complete identity is sometimes known lately (in 
application code rather than in shiro filters).
Problem : under the hood, DelegatingSubject.runAs() actually uses session, and 
calls createSession(true).

I managed to avoid this by changing sm.subjectFactory, and overriding 
getSession(boolean) : basically I return a kind of HashMap wrapped as a fake 
org.apache.shiro.session.Session, hoping this object will not be persisted 
anywhere.
I'd prefer to avoid these kind of tricks....

Just inquiring if it makes sense to runAs() without a backing storage allowing 
releaseRunAs() : the previous identity must be stored somewhere...
An alternative would be to use Subject.execute(), but this is not possible 
because I need to keep subject identity until after application code has 
returned (thus releaseRunAs() will never be called).

Do you have any idea on this point ?

Regards,

 M. Maison
