Re: Digest for google-web-toolkit@googlegroups.com - 7 updates in 2 topics

I haven't read the whole thread, TLDR.

Maybe this will help;

If you use static variables in your GWT client code, those are unique and are constrained per tab (gwt client application really).

Cookies are not constrained per tab.

So if you store the information in a static variable, you can have a user per tab, or a separate session per tab for the same user.

Session Management problem in flask application

In Firefox you can use "containers" to, well, containerize, tabs with different sets of cookies: https://addons.mozilla.org/en-US/firefox/addon/multi-account-containers/   so read all above conditions or doubts and then provide me suggestions On Thursday, April 4, 2024 at 3:13:20 PM UTC+5:30 Thomas Broyer wrote:   Not sure what more I can say.     - "Server-side sessions" use cookies, which are global to the whole browser (not per-tab), so if you want per-tab sessions you have to find another approach than "server-side sessions" - Per-tab sessions are not what most sites/apps do, so users will likely not expect it (and most users login with a single account at a time anyway, so it's mostly a non-issue). In other words, you want to do something that people are not accustomed to. More clearly: don't do it (unless you have very, very, very good reasons to) - What you should do though (that you probably don't do nowadays, which lead you to discover that behavior of your app) is to somehow check, when your app loads, whether there's already a session or not (generally, make a request to the server to get the user's information –username, etc.– and handle errors so you display the login form when unauthenticated). Opening your app in multiple tabs (after authenticating in one tab) shouldn't show you the login form.       On Thursday, April 4, 2024 at 9:55:24 AM UTC+2 aakashrathor....@gmail.com wrote:   thanks @Thoms Broyer can you elaborate more that can help me and clear what you wants to say   On Wednesday, April 3, 2024 at 6:02:06 PM UTC+5:30 Thomas Broyer wrote:   On Wednesday, April 3, 2024 at 1:16:58 PM UTC+2 aakashrathor....@gmail.com wrote:   Hello everyone, In my flask application there is some issue related to login system and issue as below 1)in flask app there are multiple users(roles) like admin ,indentor.....etc. and the problem is that if any user login on same browser where already any user logged in then previous user automatically logout and recent user logging successfully 2)if browser are different and users also different means only one user login through one browser then there is no problem it works properly 3)if browser is same and user also same then same name user login successfully but previous same user session id change 4)in any browser with same web page who running on local server all tabs session id same inside the cookies it means on same browser all tabs session id same for same web application   i current situation i face the issue related to session management ,and issue is that only one user login at same time with same browser     This is just how the web works.   If you don't want this, then you can't use cookies to maintain your session (e.g. generate some access token on the server that you send back to the client and have it send it in a header with each request to the server; the client could possibly save it in sessionStorage to store the token so it survives a page refresh while segregating it to the current tab) But note that I believe most users expect that middle-clicking a link (or right-click → open in new tab) will preserve their session, and because every web app out there shares the session across all tabs they won't even try to login with a different user in a different tab (they'll expect that their session is "detected" and reused, without seeing a login screen)   Also, BTW, this is not GWT-related (in that, it applies whether you use GWT or not).

Jens <jens.ne...@gmail.com>: Apr 04 09:24AM -0700 2)i wants to test my flask app in same browser but i wants to different user login and if new user login then previous user don't logout automatically     If you use Chrome or a Chrome based browser then you could also create two chrome profiles. Profiles are fully independent of each other and you can open two windows, one with profile A active and the other with profile B active. I regularly use that with the ARC browser (a Chrome based browser) to fully separate work and personal stuff within the same browser.   How do you want your app to work?   If you really want different users in different tabs within the same browser then you can only use session-id cookies if each logged in user has its own URL and the session-id cookie is limited to that URL. I think Google does this because Google Groups allows you to login with multiple accounts and then switch between them. But if you activate that feature then the URL is like groups.google.com/u/0/.. for the first user and groups.google.com/u/1/.. for the second user. That way they can have a different set of cookies for each URL path (= user). If you don't want that then you cannot use cookies and you must store the session-id in memory in your browser app and send it via HTTP Header manually. However doing so means that you are logged out as soon as you close the tab because the session-id is lost then.     -- J.

Aakash Rathor <aakashrathor....@gmail.com>: Apr 05 02:47AM -0700 @Thomas Broyer i implement the methods according to you but again occur the problem as below 1)if i login inside the incognito window or private window i see in all tabs or all windows session id will be same and if login user A then login user B on same browser then user A is logout automatically and if user C login then user B automatically logout so private window methodology not work correctly 2)inside the Firefox containers for multi user ,occur the same problem means if user A login and then user B login then user A logout automatically and if i use the different modules of the Firefox containers means if user A login inside the work window and then ,user B login inside the shopping window and user C login inside banking window then it work correctly but if all users login on any one window then previous users logout automatically and i checked all tabs session id is same so through this approach again i not achieved my desired output   i provide the code of my flask app so please read and then provide the suggestion i want to login all users on same browser on same system at same time but previous users not logout although user it self logout code of flask app is below #
