Forms Authentication - Redirecting To Page Other Than Default Redirect Url
Jun 29, 2010
In asp.net we specify the redirect url when using forms authentications like this:
<authentication mode="Forms">
<forms name="myApp" loginUrl="Login.aspx" protection="All" defaultUrl="default.aspx" path="/" requireSSL="false"/>
</authentication>
this means that when a user log in, will be redirected to "default.aspx" using this method
FormsAuthentication.RedirectFromLoginPage(IDTextBox.Text, RememberCheckBox.Checked);
Now is it possible to make the user choose which page to be redirected to prior to login? for example the user chooses from a list the page to login to prior to login then when authenticated be redirected to this page instead of the default.aspx page. is that possible and if so how can this be done?

I am in the process of designing application in case user authentication if failed i need to redirect to default page (NT Authentication). Is there any way you can redirect the user on IIS if the user is fail go through the NT authenticaiton at IIS level.Options 1 : Always land the user to defalut page and validate there and redirect to site based on the access give the directory level access. I am looking if there any options to let the user to default page in case user access is denied.

I am using VWD 2010 on a windows 7 64 bit install. Using forms authentication I am not being redirected to the login page when not authenticated yet. Even if I start a new web site from template, clear out all cookies, I still go directly to default.aspx. The LoginView control displays the anonymous template verifing I am not authenticated.
configuration why redirection doesn't occur? Remember I am trying this with New Web site template with no mods so I don't think config issue is within application code.

I have been trying to set the default url but it is not redirecting to the page that I want. The defaultUrl="admin/Home.aspx" is keeping redirecting back to the login.aspx Below is the code i am doing in the web.config
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="20" defaultUrl="admin/Home.aspx" />
</authentication>
the url after being redirected is as follows
/Login.aspx?ReturnUrl=%2fadmin%2fHome.aspx
what do the %2f mean?

I just observed something with the .net 3.5 VS2010 Login control. It seems to response.redirect is doing
something I cant explain:
[Code]....
after I hit the response.redirect all that is happening is that I stay on the login page and the URL
changes to http://localhost:50324/Account/Login.aspx?ReturnUrl=%2fAccount%2fAdmin%2fApproval.aspx
Why am I not properly redirected? I used server.transfer, that put me on the right page (Approval.aspx) BUT as soonas I clicked a button, I was back at Login.aspx.

In our application we are using forms authentication, we have given defaulturl also in the config file. But the problem is that it is not getting redirected to the default url when the session timeout is occuring.

I am using forms authentication and authorization through roleManager. I have two Roles - "Customers" and "Employees". The redirection to the default page for the "Customers" role is working fine, but I get an oledb error stating that one or more parameters are not being passed when I redirect a user from the "Employees" role. The following is the code in login.aspx that handles the authentication of the user:
If myReader.Read() Then ' We have a match
If myReader(1) Then ' This is true if an Employee and false otherwise
If Not Roles.IsUserInRole(logInUser.UserName, "Employees") Then
Roles.AddUserToRole(logInUser.UserName, "Employees")
End If
ElseIf Not Roles.IsUserInRole(logInUser.UserName, "Customers") Then
Roles.AddUserToRole(logInUser.UserName, "Customers")
End If
FormsAuthentication.RedirectFromLoginPage(logInUser.UserName, logInUser.RememberMeSet)
Else
Response.Write("Invalid credentials")
End If............................................

When I tested web site on SEO Tools in IIS7 I get this SEO Error: The page contains multiple canonical formats. The page with URL "[URL]" can also be accessed by using URL "[URL]".Search engines identify unique pages by using URLs. When a single page can be accessed by using any one of multiple URLs, a search engine assumes that there are multiple unique pages. Use a single URL to reference a page to prevent dilution of page relevance. You can prevent dilution by following a standard URL format.
Recommended action: Pick a canonical URL format for your site and then ensure that all the links in your site follow that format. (For example, always use lowercase letters.) If an external link that points to your site does not use the canonical URL format, use permanent HTTP redirection to redirect site visitors and search engines to a canonical equivalent of that URL.
I tried to solve this by redirect page to a default.aspx. The problem is that HttpContext.Current.Request.Url.ToString(), always shows [URL] So I can't detect if url typed in browser is only [URL] or [URL] I know that that can be solved in IIS7, but I can't access it to do that in hosting server. Is any solution in ASP.NET to redirect to default page any time when in browser is typed only domain name?

I have an application that uses ASP.NET Forms Authentication. For the most part, it's working great, but I'm trying to add support for a simple API via an .ashx file. I want the ashx file to have optional authentication (i.e. if you don't supply an Authentication header, then it just works anonymously). But, depending on what you do, I want to require authentication under certain conditions.
I thought it would be a simple matter of responding with status code 401 if the required authentication was not supplied, but it seems like the Forms Authentcation module is intercepting that and responding with a redirect to the login page instead. What I mean is, if my ProcessRequest method looks like this:
[code]....
Then instead of getting a 401 error code on the client, like I expect, I'm actually getting a 302 redirect to the login page.
For nornal HTTP traffic, I can see how that would be useful, but for my API page, I want the 401 to go through unmodified so that the client-side caller can respond to it programmatically instead.

I am a beginner of asp.net..I currently have a login page with forgot password link button on the bottom of the screen. I am also using forms authentication to prevent an unauthorized user from accessing the other pages. The authentication seems to be working fine except for one thing. It prevents the user from accessing the password recovery page once the user click on the link button. How do I allow all users access to the login/password pages and also prevent them from viewing the other pages if they are not authenticated?The code below is to prevent from other anonymous view other pages without access. But i got no idea on how to allow them to access password recovery page...
<authentication mode="Forms">
<forms loginUrl="/Presentation/Display/Login.aspx" name=".ASPNETAUTH" protection="All" path="/" timeout="120" cookieless="UseDeviceProfile" slidingExpiration="true"/>
</authentication>
<!-- This section denies access to all files in this application except for those that you have not explicitly specified by using another setting. -->
<authorization>
<deny users="?"/>

IIS6, ASP.NET 2.0, No Forms Authentication I'm calling Response.Redirect("~/foo.aspx"), but the default document ("Default.aspx") for my site is appearing. To make matters worse, it only happens intermittently. Sometimes the redirect displays the right page.
I've checked session state, and I don't see any values in the web.config (that is, I'm assuming I'm using the 20-minute defaults).
There's foo.aspx and foo2.aspx (and the default document, Default.aspx). All pages extend from BasePage, which extends Page.
BasePage has a property named ReturnPage:
protected string ReturnPage {
get {
if (Session["ReturnPage"] == null) {
Session["ReturnPage"] = "";
}
return Session["ReturnPage"].ToString();
}
set { Session["ReturnPage"] = value; }
}
Users click on a LinkButton on foo.aspx, and the click event handler ends with two lines of code:
ReturnPage = ResolveUrl("~/foo.aspx");
Response.Redirect(ResolveUrl("~/foo2.aspx"));
The Page_Load of foo2.aspx has problems, and its error handling calls Response.Redirect(ReturnPage).
When I view the response headers of foo2.aspx, the 302 location is string.Empty (that is, there isn't one). That same response header has the same ASP.NET Session ID as the response of foo.aspx.
And remember -- this is intermittent. Sometimes, you can click on that LinkButton and go effortlessly to foo2.aspx, no problem. You can process the click with the exact same data once, and it will fail. You'll navigate from the default document (Default.aspx, where you were sent by the "bug") back to foo.aspx, click again with the same data (the same row in the grid/table -- the same LinkButton, essentially), and you'll be redirected to foo2.aspx without issue.

the default ASP.NET Forms Authentication cookie sets it's name as ".ASPXAUTH". Notice the first character is a period? Is there a particular reason for this? Like, does this have an impact on domain names or subdomains for the target domain.
Or is it purely some random thing an MS dev person came up with (maybe to help out the ordering of the cookies, when they were debugging or something .. as text with periods prolly get listed before other strings)?

I have an ASP.NET 3.5 intranet website which has a default page with a menu and when the user clicks on a menu item, I display the page for that menu item in an iframe embedded within the default page. but if the user types the URL of a page directly in the browser, then I would like to redirect him to the default page, because all the content pages do not have a menu. (Master Pages will solve this issue, but I can't use Master page here for a reason and don't want to go into those details). how to find out if user has arrived at the page directly by typing the URL or by clicking on the menu item, so that I can decide whether to redirect or not? Is this possible to find out? btw this is an intranet site and no login is required.

we would like to redirect the user to a given page if the authentication to our SharePoint site fails (i.e. the standard windows login prompt pops up three times - we are using windows authentication). No matter what option we try it always ends up bringing the user back to a blank page.
We have tried writing a HttpModule (and catch the if Response.StatusCode = 401), which doesn't seem to fire any events if the user is not authenticated. We have tried writing a HttpHandler, but of course we can redirect the user if there is an error code but can't continue onto the desired site if not. We have tried doing the following in the web.config:
<customErrors mode="Off">
<error statusCode="401" redirect="http://social.msdn.microsoft.com"/>
</customErrors>
Which doesn't work, again taking us to a blank page.

In an asp.net mvc website, the site has enable forms authentication. The form login page is located in an area such as:
Area: Area1, Controller: Account, Action: Login
When a user is not yet authenticated and click on a link that requires authentication, the user is redirected to the login page. This does occur and redirect to the login page specify above. However during debug, it was found the area value is not included in the RouteData.Values object. That is, the RouteData.Values object has ONLY the follow value:
Controller: Account
Action: Login
In this case, it is presumed that the MVC application by default searches for the appropriate controller and action without consideration for including the area value. On contrast when I direct click on a link that directs to login page, all processing occurs as expected, i.e. the area value is included in the RouteData.Values object. Is there a work around for this?

I'm using sessions to track user name. I assign Session["userName"] in my login procedure. The sessionn gets timeout in about 15 minutes. What I need to do is, if the session timeouts I need to redirect the page to the Default.aspx page.
How can I do this? Any code example would be great.

Suddenly, IIS 7.0 is redirecting every request for the root of any domain hosted on the box to ~/Account/Logon, which is our Forms Authentication redirect. Additionally, some JavaScript and image requests are being similarly redirected, but not other aspx pages.
EDIT: It turns out that something has gone wrong with the disk permissions. Can anyone point me to the way things are supposed to be in Windows Server 2008 for a standard ASP.Net installation? The disk permissions are out of whack now.

I have a logon/register control that is on several pages. Users are logged on with code: - FormsAuthentication.SetAuthCookie(Userid, False) Response.Redirect(Request.Url.AbsoluteUri) ' Round trip is necessary to complete logon
All this was working OK, except that there was a problem with Internet Explorer users: if their browser had the default privacy setting the authorization cookie was rejected. There was no message, but they were not logged on. See [URL] To try to solve this problem I changed to cookieless authentication, but now the logon control doesn't work. The problem is that after cookieless authentication the URL changes from
[URL]
However Request.Url.AbsoluteUri remains http://localhost:3641/TestGDB/login_pages/home2.aspx even after the logon, and so with cookieless authentication the user is not logged on as there is no authentication ticket in the redirect URL.
The problem is "solved" by changing the Redirect statement to Response.Redirect("~/login_pages/home2.aspx") which works perfectly for this particular page, but is obviously wrong when the control is on other pages.
How do I write "Response.Redirect(current page)"?
