Sessions not working in IE 7

[eluser]kyko[/eluser]
I've found the solution to my problem. Apparently, IE7 drops sessions that are set when your machine's date and time is not correctly configured. Follow this link, No Cookies in IE??. I hope it made your day as it made mine.

Thanks for this great community!

Just thought I'd note that I've been having a problem with CI sessions and IE7. When I log in to a project I'm building (that does security checking using CI session variables), all works fine in Firefox. However, with IE7, once I login and try to navigate to a protected page, the session seems lost and I am sent back to the login screen. I've found that by adding a trailing slash "/" to the URL of the page I am unable to access, everything works fine. I have no explanation as to why this works, but hope that someone else may find it useful.

Also wanted to note that this only happens on my home computer, but IE7 on my computer at work works fine. Tried changing the variable name from ci_session to cisession, but this appeared to have no effect.

Hay I confirm " _ " Is the problem. I just change the name without " _ " and works great


Cheers ...


Thanks for this solution

What version are you on, Justin? Again, I'm not buying it. I think your problem may be something that we fixed in 1.7.

I searched the forum and found this out.

The problem:
Safari and IE7 didn't accept cookies

Fix:
My server time is way way late than what I have on my pc. I changed the

Code:

$config['sess_expiration']        = 7200;

to

Code:

$config['sess_expiration']        = 72000;

and it fixed the problem.

I had the same problem.
I tried everything and I finally found the problem:

The date of server was incorrect (it was one day in the past)

Ie, Safari and Google Chrome probably check the local and server date.

Thanks for closing the loop, Chalda, I knew it just wasn't making sense, particularly after we fixed the bug with the size of the cookie when using db sessions.

The underscore problem is not a CI problem. Is a problem with Internet Explorer (and Safari too as I know) with domain name's that contains the underscore "_" character. When an user of this browsers, try to login in a page like http://dev_domain.example.com, the cookie can't be stored.

I'm testimonial of this bug/problem in a non-CI page (page built in PHP from the scratch).

There is a KB page in MSDN but I can't find it now... However, you can read a list of user comments about it in the PHP manual:
