Security :: Logout Authentication Works One Time Only?
Feb 7, 2011
I Have gotten the logout authentication to work. THe problem was that after logout u can back browser back into the app. Now it does redirect to the app login screen, but this is good only one time. If you re-login to the app, relogout, and then try to back browser in, it goes back to the running app.
I would like to know how to get this logout process to work all the time. here is some code i have pertaining to the authentication process:
Need the code for the login /logout in my sample project and how to attin logout in the all pages. dont mistake me as i am learning (fresher) the asp.net 2005
first i want to know most of the e-mail like gmail,yahoo,hotmail etc.. they are all uing https when we comes to login area.. why there are using on that time only https...i also need to implement same in my web application...
I have a web application build in asp.net and using a custom membership provider for authentication and authorization. Everything works fine except when the user click on the logout link to log out of the application and being redirect to a default cover page, if the use click on the BACK BUTTON on their browser, it will actually go back to where they were before and the data will still show up.
Of course they can't do anything on that page, click on anything link they will be redirect to a login page again. But having those information display is making a lot users confused.
i am just wondering if there is any way i can either clear the browser's history so use can't go BACK, or when they click on the back button and have them redirect to the login page.
i want to have several domains A, B, C where a user can enter his username and password to login to a common main domain D.
So the user goes to A, B or C, enters his username and password, clicks the "login" button, and is then on the main domain D in a logged in/authenticated state. Then the user does the things he wants to do, and then clicks the logout-button and is then returned to the original domain that he came from, be it A, B or C.
What is the best way to do this?
I currently use forms authentication in ASP.NET 4.0 (C#).
I am doing office management system in web. here i want to display the employee login and logout time in calender (like reminder notice) every day. how to display all the database value to calender date wise.
By using above query its fine to save logout time in database, if the user unfortunately close the browser without logout then how to store logout time in database...
I have datagridview with paging enabled. But when I want to move from page to another page in the grid, then it only works when I press the 2nd time on some other page. I read some on the internet that I need to bind the data of the gridview but the thing is, I cant bind the data again because the gridview was filled with data in the page_load from querystring and I dont really want to go over the querystring again in the PageIndexChanging function.
Since I start hating postbacks, I use WS or PageMethod for every client to server process. I did same for Logout but Im not sure in this.
I wrote code like this
//In WS
[Code]....
//on aspx
[Code]....
everything working fine, but I have some kind of feeling that I'm missing something(like calling any other method) ? I just wanna make sure as its for security purpose.
I have a login page and a default page to be redirected to after login. when I clicked on thew logout button in the default page it correctly redirects to login page. But when I click the back button in the IE I can again see the protected default page( in mozilla everythng is OK, no problem but in IE this problem occurs).
give me a working snippet for logout..I'm fed up of using all session.abondon() bla bla.. Even after logout wen i click back button i can view my page.. How to over come this..
This could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.
I set authentication mode to Windows in the web.config and I enable Windows Authentication and disable the Anonymous Authentication in IIS 7 on win 7, but HttpContext.Current.User is always null.It works fine when I host the web app in IIS 6.0.
1. login 2. mailbox.. 3. that is redirected after logout.
i used sessions here...and session.Abondon() for logout.. bt if we go back from the browser button provided top-left corner, then mailbox is opened again...without even logging in..... its dangerous.
I got a problem with my login and logout for my asp.net website, whenever i try to login or logout, it will load the page i direct it to first then i have to reload the page again for the login or logout to work. First my login i am using a login control to do it and also using this code to go to another page:
to MVC musicstore sample in .NET 3.5. Clicking in "Log out" hyperlink calls javascript postback function. Current page is re-dispalyed (master page is not shown) and Log out message is still displayed. Log in link does not appear How to fix this so that log out really logs out ?
In the site I am building we have standard users and superusers. A superuser can delete another user from the system and this should result in that user being logged out (if he/she is currently logged in). We use the Membership provider. Or actually the superuser doesn´t delete the other user completely but instead sets his/her as inActive by following code:
[code]...
But, that should not matter... What I want to know is how to make the affected user being logged out. I don´t need a popup or anything to be shown to the other user that he/she is just logged out, it is enough to check if that user is logged in when he/she tries to move to another page on my site.
