Proposal:

Return the remaining time for the end of the session by REST API. This will
add a functionality in the UI, that will popup a warning asking if user
wants to keep it logged.

More information on issue: https://github.com/kimchi-project/wok/issues/133

Doubts:
How i will return this on the header?

Not sure, but googling a little bit I found that HTTP Response Header
has a field called 'Expires':

https://tools.ietf.org/html/rfc7234#section-5.3

For more information about Response Header Fields:

https://tools.ietf.org/html/rfc7231#section-7

Look at render() function in src/wok/template.py
Please, define the header name to do no block the UI development.

Where timeout of authentication (session) is ?

'session_timeout' is a variable present in Wok's configuration file
(src/wok.conf.in line 27) and set in src/wok/config.py.in (line 273).
You can get it's value in backend, just importing wok.config and reading
it's value:

import wok.config as config
session_timeout = config.config.get("server", "session_timeout")

No no!

This session_timeout is the number of minutes that a session can remain idle before the server terminates it automatically.

That value needed by Ramon is related to the last access which refreshed the session.

Ramon,
In that case, the information is hold by cherrypy.session

cherrypy.session is a dict with the following data:

[('username', u'guest'), ('robot-refresh', 1469022245.734541), ('roles', {'templates': 'user', 'guests': 'user', 'network': 'user', 'administration': 'user', 'storage': 'user', 'dashboard': 'user', 'system services': 'user', 'updates': 'user'}), ('groups', ['guest'])]

the 'robot-refresh' contains the timestamp from the last requested.

You can check check_auth_session() in src/wok/auth.py to understand how that value is set (time.time())

Also, do not use 'robot-refresh' hardcoded in your code. Use the constants defined in src/wok/auth.py

So to get the amount of time the session will be alive you need to do:

current_time = time.time()
last_request = cherrypy.session[REFRESH]
session_expires = last_request + (session_timeout * 60)
still_alive = session_expires - current_time

I hope it helps you.

>From what Peter requested at https://github.com/kimchi-project/wok/issues/133#issuecomment-232752799 he wants to have the time the session ends.

So it would be cherrypy.session[REFRESH] + (session_timeout * 60)

Please, consider the right data format when doing that count.

Also to renew the session we can use the API /tasks
