IE session issue in Codeigniter

You can try following things:

1) If session is working fine in your system but having problem on the server,
then set the time of server. the problem occurs due to difference in time.

2) try to set the path like
$config['cookie_domain'] = "meerutwala.com";
$config['cookie_path'] = "/app";

because IE need domain name for cookie.

3) Try this also
change
$config['sess_cookie_name'] = 'ci_session';
to
$config['sess_cookie_name'] = 'cisession';
because IE don't like underscore in its name
4) if nothing is working for you then go for native session :(
