in http.py file there is this method

def session_gc(session_store):
    if random.random() < 0.001:
        # we keep session one week
        last_week = time.time() - 60*60*24*7
        for fname in os.listdir(session_store.path):
            path = os.path.join(session_store.path, fname)
            try:
                if os.path.getmtime(path) < last_week:
                    os.unlink(path)
            except OSError:
                pass

if you deleted the random condition the session will expire after a week , but i would like to understand why this line is existed , why the session expiration is depended on a random number

thanks

I checked the answer I found on this forum (help.openerp.com/question/7363/settings-to-session-timeout) but it does not look right to me. The selected answer will only terminate the session after certain time (10 min in the answer above) but without looking at idle time, this means it will kill the session after 10 min even if the user is still working. I tried the solution mentioned By Mr.Shokri and it worked for me, I even reduced the time without removing the line like

if random.random() < 0.1:

and lt worked also. I agree with Mr.Shokri, if this line is preventing the code from working, I really want to know why this line exists in the first place. Thank
