Security :: FormsAuthentication.SignOut() Doesn't Work For Previous / Back Button?
May 13, 2010
I have a Default(contains the sign-out button) and Login page, once the user is not authenticated, it will always redirect the user to login page.
So the scenario is when the user hit the sign-out button it will redirect him to the login page which is good. My problem is, when the user hits theprevious or back button from the login page,it will still read the authorization cookies and redirect him to the default page. which should not be the case. the user should be redirected to login page when authentication is invalid.
I've read some solutions on the net, but still it doesn't work for me. below are the codes I've used for my sign-out function
[Code]....
By the way, when the user is authenticated, the previous or back button is available/enable for the user.

I have done some modification and customization with List.aspx under Dynamic Data.
I must have messed up some controls or events somewhere.
Everything works well except that GridViewPager buttons (|<, <, >, >|) does not bring me to the next or previous page. It stays at the same page.
But if I manually type in the page number into the page number field and press enter, it works brilliantly. The gridview refresh to the correct pageindex.

I am using ASP.NET, the web page is abandoning and clear session when a user click logout link but they click the back button and it is still showing the previous page. How can it prevent the previous page after logout? on Logout.aspx load im using this code
Session.Clear();
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1D);
Response.Expires = -1500;
Response.CacheControl = "no-cache";
//----- Second Technique : To Stop Caching of Secure Pages.
Response.Cache.SetCacheability(HttpCacheability.NoCache);
FormsAuthentication.SignOut();
if (Session["UserName"] == null)
{
Response.Redirect("login.aspx");
}
Session.Clear();

I have an MVC app that uses [Authorize] to protect the private bits. When I select the SignOut() URL it signs me out but if I hit the back button on my browser the it goes to the secure page and even lets me use the form. The action takes place and then it shows that I'm signed out. The problem is that it performs the secured action (inserting a row into my database). Then I can use the back button again and do it all over. If I use the back button after logging out and hit the browser refresh it does show I'm logged out and refuses me access to the secure page. Am I missing something important? It seems like it could be a really big security issue.
public ActionResult LogOff(string ReturnUrl)
{
FormsAuth.SignOut();
if (!String.IsNullOrEmpty(ReturnUrl))
{
return Redirect(ReturnUrl);
}
else
{
return RedirectToAction("Index", "Page");
}
}

Is it possible to validate a user's Username + Password without logging them in? I understand a usual login block will look like this:
[code]....
With the Membership.ValidateUser() call setting the cookie for the response.
However, there are some additional checks I'd like to perform after the password is confirmed. (Pulling out an expiry date for that user, for example).
Is there a way to do it without just calling FormsAuthentication.SignOut(); after invalidating the page?

I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?

Created in VS2008
The login page is created with the masterpage and it has the header picture.
After Logout or run FormsAuthentication.SignOut();
The login page is not showing correctly with the header (from master page).
And the setting on the web.config as below:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
Is there any reason why the header from masterpage can not be viewed from the login page?

I have four pages and user enters certain information and navigates to the next page. In the last page, when user clicks on submit button it will redirect him to the confirmation page. Once the user is in the confirmation page and clicks on back button, all the fields in the previous pages must be non-updatable. Note: User can use the back button to view his previous data but not-updatable anymore.

I've created a Sign Out link on my page, just like the one you see on the top right hand corner of this forum.
This is the code i use :
<asp:HyperLink NavigateUrl="~/Login.aspx" ID="hypSignOut" runat="server" Text="Sign Out"></asp:HyperLink>
However, after signing out, I click the back button on my browser, I can still go back into the site. How do I prevent this?

I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown.
public void ShowAlertMessage(String message)
{
string alertScript =
String.Format("alert('{0}');", message);
Page.ClientScript.RegisterStartupScript(this.GetType(), "Key", alertScript, true);
}
What do I need to do so it works on partial post backs?

Before I go the route of using hidden fields or something similar, is there any way to send back to the server changes to the disabled state of an ASP.net Button control? I have a Button that is initially enabled and I disable it via jQuery on the client. Works great. The only problem is when I do a PostBack the server still thinks the Button is enabled and sends back a response that changes it back to enabled. Why doesn't the ViewState send back the current disabled status of the Button? Is there a way to force it to postback the changes? Other ASP.net controls, like the CheckBox, do send back the state changes to the server. Seems odd to me.

I have a problem. I can't get current logged user to my application. Everything is fine on localhost. When I deployed an application
on IIS, it stopped working. I have Windows Authentication Enabled on my IIS. For every account which uses intranet, logged user is the same now, and it's an administration account.
Why application doesn't get real logged user, but administrator account ?
