Answer / mahesh
#1) Session serv path / session ina file
#4) When A user login in one system and in perticular
browser means, session id set for A user with browser type
and system ip address. similarly B user had separate id. So
system wont get confused.
If A user get logged in the one browser at one system means,
A user cant log in with another username in same browser in
same same system. Because first username is already logged
in... You can logged in different browser in same system.
If you had doubt means try it..
#3) There is no relation between server crash and session
files upload. Session will timed out according to session
time set.
