This has been asked before, but I haven't seen anything posted about it in years, and I'm running into the problem now.
Steps to reproduce:
Log into my site (C# 6, angularjs, .Net Framework 4.8)
Once logged in, use Cookie Editor to export the session cookies in the browser (using Chrome in this instance, but that doesn't matter.)
Log out
Using Cookie editor, import the copied session cookies.
Refresh the page... voila - I'm logged back in.
So, my code for logging out does all the "get rid of stored cookies" things it should: loop through all the cookies and expire them; clear the Request.Cookies; Abandon the Session; Clear the Session; RemoveAll on the session.
But when you paste that dang .ASPXAUTH cookie back into the browser... whammo. Logged in.
I'm not sure how to prevent this, and could really use the help.
For specific reasons I'm logging the user automatically, and set the remember_me cookie so they stay logged in.
They hit a route like my-app.com/my-login?params=XYZ
I call Auth::login($user, true);
I redirect them to a page where they are logged in
It works everywhere, except on iOS Safari (for some reason). There, it logs in, but doesn't remember the user. However if I refresh the final page just after login, it remembers the user!
Any idea why? How/when is the remember_me cookie set in the HTTP response?
10 years from now it was a problem
Safari doesn't set Cookie but IE / FF does
Some Safari old versions like (v. 7.0.6) would ignore a cookie. The cookie header looked perfectly fine, almost identical to another cookie which was remembered.
The culprit was the previous cookie header having a malformed expires value. Safari's handling of broken cookie headers is evidently not as robust as that of the other browsers.
So try to use newer safari
I am building a small web application and in my application I am using the session object to store information across calls to server. This works quite fine in Firefox \ Chrome\ IE, but it seems to fail in Safari. In Safari the session keeps forgetting that I've stored values in it.
Why is this happening? what can be done?
The session is based on an id stored in a cookie. The server uses this Id to link to your session on the server. It's highly likely cookies are off here. Load up fiddler or turn on tracing to see what cookies are being sent over... You should see the one with aspnetsessionid in it, if not your browser prob has them turned off.
You may also want to take a look over here: Facebook API and Safari
Looks like, if any redirect is sent when you are establishing cookies, they will be viewed as 3rd party cookies and could cause issues with your server-side.
if your settings on Safari are set to not allow cookies, then this fails. I have just had the same issue on an iphone web app im writing. I enabled cookies and all worked fine.
The whole idea of the Session is that the values are stored server-side. Safari can't possibly cause the server to forget something. Either the value wasn't ever stored in the Session or Safari is failing to render the Session value.
Trying using a debugger to confirm if the Session holds the correct value when passing the value into the Session and when you're attempting to retrieve the value from the Session.
Is it possible for Safari extensions to save cookies locally instead of using the browser's cookies? The problem with HTTPS ajax requests bringing up a login popup is starting to rankle me. I know how to login to Google services from a command line script using curl and perl/php. If I can save my cookies somewhere on the local filesystem I can avoid all this hassle.
Nope. Safari extensions have no access whatsoever to the local filesystem. You can only use cookies directly from the browser or local storage.
Generally speaking, when given a cookie that has no expiration period, modern browsers will consider this cookie to be a 'session cookie', they will remove the cookie at the end of the browsing session (generally when the browser instance closes).
IE, Opera, Safari and Chrome all support this behavior.
However firefox (3.0.9 latest proper release) appears not to follow this rule, from what I can tell it doesn't expire the cookies when the browser is closed, or when the user logs off or restarts the OS..
So, why does firefox refer to these as session cookies, when they last aparently indefinitely?
Does anyone know how Firefox handles session cookie expiration?
This is apparently by design. Check out this Bugzilla bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=443354
Firefox has a feature where you close Firefox and it offers to save all your tabs, and then you restore the browser and those tabs come back. That's called session restore. What I didn't realize is that it'll also restore all the session cookies for those pages too! It treats it like you had never closed the browser.
This makes sense in the sense that if your browser crashed you get right back to where you were, but is a little disconcerting for web devs used to session cookies getting cleared. I've got some old session cookies from months ago that were set by sites I always have open in tabs.
To test this out, close all the tabs in your browser, then close the browser and restart it. I think the session cookies for your site should clear in that case. Otherwise you'd have to turn off session restore.
Two ideas :
You have a problem with your session manager (the one included in FF3 or one included in an extension, like tabmixplus)
Use Firebug + FireCookie (https://addons.mozilla.org/en-US/firefox/addon/6683) to debug !
This should work. I used to be one of the cookie module testers, and I don't think there is any design reason this would behave differently (although if you crash, the session cookies might be designed to live on when you restart...)
Are you viewing the cookies in the "Preferences" menu > "Privacy" Tab > "Show Cookies..." button?
Also, have you tried a new profile?
I disagree with meandmycode above.
The HTTP spec https://www.ietf.org/rfc/rfc6265.txt talks about what a client should do with Set-Cookie headers with Expires:
If the server wishes the user agent to persist the cookie over multiple "sessions" (e.g., user agent restarts), the server can specify an expiration date in the Expires attribute. Note that the user agent might delete the cookie before the expiration date if the user agent's cookie store exceeds its quota or if the user manually deletes the server's cookie.
The logical extension of this is that the ONLY way the server has to require that the browser does not maintain a Cookie on exit is to set no Expires value (i.e a session cookie). If a browser does not honor that semantic then its not honoring the server's response.
Essentially the user agent is deciding to ignore the server request and act as if an Expires value had been set.
This is a bit of a concern in shared user environments. If I set a authentication cookie that is set to expire at the end of the session. This will persist in Firefox after the browser has been closed and another user starts up Firefox. Cookies are set with an expiry date for a reason!
I'm flummoxed that Mozilla have left this as it is for several years.
OK.. so I quit FF and switch off the PC.
Next day FF starts and opens the last set of pages (nice handy feature) BUT it restores the sessions and I'm logged back in to sites which have no "save my settings" feature.
I know because they are sites I built.
Whatever I do with php ini settings the sessions are restored.
They absolutely should not be restored.
Pages yes, but sessions with cookie ini set to '0' no.
I don't understand why this is not flagged as a security hole.
Sure I can do some additional checking on the server side, to see if a login should be allowed, based on time from last log in, but it shouldn't be needed.
A session should NOT persist.
FF is manipulating cookie expiry settings.
In my case, it was because of pinned tabs that automatically restored the session even if this option was disabled in Firefox settings. So if you unpin the tabs, the session won't be restored.
Well it is disconcerting to me. My system is set up so that users can hit EXIT whereby I destroy all session cookies. But if a user closes the browser without actually choosing to Exit, I'd like the session cookies cleared.
I actually tested it with Google Chrome, IE 9, and works fine. But Firefox is reluctant to kill this "session" (as reported by Firebug) cookies.
OK. This is what I did. I chose Exit from FireFox main menu and from then on, did it fine as expected (Dont know why).
