A cookie is associated with a URL path. That means that
http://mysite/a/b
will by default have a different cookie then
http://mysite/a/c

In order to share a cookie between modules, you must set SessionCookiePath
at the start of the program:

SessionFactory.SessionCookiePath:='/';

This will emit a cookie that has / as the path.
