Almost: the filecontext defines tha path for the state files,
tells websh to look for the session id in the url param sid and
defines a command to create a unique session id
The idGenerator has to be defined still (does not have to be an
increasing integer but could be anything)
If it is created with [web::filecounter idGenerator -filename
/tmp/sid.seq] it will create increasing numbers for session ids. but
you can provide your own generator. (Just write a proc that returns a
new session id and supply it with the -idgen option)
To actually pass the sid parameter from request to request, use
web::dispatch -track sid
and to really get a new session or load an existing ession use the
corresponding commands of the filecontext (in the example above you
created "state", so state::init state::new etc ... will be the
commands you need).

No. -idgen is used, if you instruct filecontext to create a new
session id.
If no id is in the URL (which is defined by -attach to) and you don't
want a new context to be created, -idgen has no effect (but you'll
never get a new id)

ok, correct me if I'm wrong.
The option -idgen is used only if filecontext cannot find the parameter sid
from the url?
thx,
Jerry
