ie session disappear or IE browser issue

[eluser]Unknown[/eluser]
Ff3.0 the problem has not.
Ie6, ie7 apply to the login page after the first session but moved to another page disappears.
What is the problem?

My config.php

Code:

$config['sess_cookie_name']        = 'cisession';
$config['sess_expiration']        = 7200;
$config['sess_encrypt_cookie']    = FALSE;
$config['sess_use_database']    = FALSE;
$config['sess_table_name']        = 'ci_sessions';
$config['sess_match_ip']        = TRUE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']         = 300;

$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']        = "/";

FF on pages When reload $this->session->userdata('last_activity'), the value of not changed.

But IE7 on the same page when reload $this->session->userdata('last_activity') appears in the value of the current time value.

The IE browser issue?

IE was an error on my computer.
And no more than other computers. T.T

I've just experienced a very similar problem, it seems there is a problem with CI Sessions and Internet Explorer.

someone recommended 'native sessions', which appear to work correctly

Also make sure that your server is at the right time otherwise it will not work on Safari and IE.

I have same problem with this
I tried the site in FF and IE6, it works fine. But when I tested it to IE7, I am redirected to login page.
I am always clearing my cache and I set to allow cookies, but nothing changed.
Please do help…
By the way, the site works great on a local server using IE7.
Thanks in advance…

P.S. The thing I've made to work in IE6 is that I checked my server time, and found out that it was 13 hours late. I changed the value in the
$config['sess_expiration']
and added 13 hours plus an hour for my session expiry.
It works in IE6.

The same thing I applied in IE7 but even I lengthen my session expiration, the session still expires(on my thoughts)..
Can anyone help?
Thanks!!!
