Multi-Token Statements
The @( ) syntax enables a code block to have multiple tokens. For example, we could re-write the above code to concatenate a string and the number together within a @( code ) block
I'm updating my old .aspx views with the new Razore view engine. I have a bunch of places where I have code like this:
<span class="vote-up<%= puzzle.UserVote == VoteType.Up ? "-selected" : "" %>">Vote Up</span>
Ideally I'd like to do this:
<span class="vote-up@{puzzle.UserVote == VoteType.Up ? "-selected" : ""}">Vote Up</span>
However there's two problems here:
vote-up@{puzzle.UserVote .... is not treating the @ symbol as a start of a code block @puzzle.UserVote == VoteType.Up looks at the first part @puzzle.UserVote as if it's supposed to render the value of the variable.
I'm using the 'Configure Data Source' wizard to connect to my database and show the dataset in Gridview. I want to be able to update, insert and delete entries but am unsure how to build the query. I can write simple update statments to change database entries but how can I do this for entries that have been changed within the gridview?
View 6 RepliesOur current application is working fine but when you try to misbehave like we found out that When login with same user in multiple tab with different organization(there is a organization dropdown in the master page which sets the cookie whenever it is changed.) in tab one it is org 1 and tab 2 it is org2 , cookie has the later org 2 in it but when we go back in tab1(which had org1) and save the record org 2 will be saved with the record So can some one share some sort of a checklist with us which address these types of problem.
View 3 RepliesWe have a simple ASP.NET app that uses the ASP.NET SqlMembershipProvider and all is great.
We want to create a second app on the same server, also use the SqlMembershipProvider, but a different "applicationName" so that the user accounts between the two apps are kept separate.
It looks like this would be possible by making the two different app domains (ie they each have their own web.config), but I'm hoping to just put them in different directories so I don't have 3 web.configs (one for each app, and the main one) that all have to be kept synchronized. So what I'm after is:
/web.config
/APP1 (uses membership provider in /web.config, with userlist A)
/APP2 (uses membership provider in /web.config, with userlist B)
It looks simple to define multiple membership providers that use a different 'applicationName' value.
But how do you tell the system.web.authentication node which membership provider to use?
when i read msdn.
i saw 2 things token and formsauthentication ticket..
can anybody tell me the Difference between token and FormsAuthenticationTicket ?
here is an article here:http://alt.pluralsight.com/wiki/default.aspx/Keith.GuideBook/HowToGetATokenForAUser.htmlIt's not clear why I would need it ? Is it for ASP.NET or also Winform ?
View 1 RepliesI'm working on a solution to part of my companys site that is done in 2 different languages. My part of the project is in ASP.NET, and the login portal is in a different language. We pass authentication credentials by storing login information in the database on the portal page and then sending a corresponding token to the URL in the page written in .NET. Almost all the tutorials and articles I've read about security for ASP.NET, and most languages, the message has generally been "just use the built in stuff and don't mess with it".
I have code that takes the token, goes into the database and gets the user details.. what do I do then to integrate that into the built-in security stuff for ASP.NET? I'd like to ultimately use Action Filters for authorization on my controllers.
We have a SSO authentication service that other externally facing web pages and services use to authenticate users. A user tries to reach a service, if no cookie is found containing an authentication token, they are redirected (HTTP 302) to the SingleSignOn authentication service. The auth service does it's work, and redirects the user (HTTP 302) to the original URL with their encrypted authentication token in the URL. Great. How can I invoke this from a WCF POX service? No SOAP here, just HTTP GET/POST with XML responses.
What I'm currently doing is, in each service method implementation method, checking the headers for the cookie. If the cookie exists, verify the auth token and process the request. If the cookie doesn't exist or the auth token has expired, then respond with:
[Code]....
That works, but isn't integrated with any of the WCF features, and requires me to manually code for a whole bunch of scenarios. Is there a way I could implement this using these classes:
[Code]....
or use some other means that checks each request to the service? I've been reading pages like: How to: Create a Custom Token, but I don't see how it applies to my needs. I'm looking into this because I have some time before my project kicks off, and I'd like to implement this project correctly and learn about WCF as much as I can.
I'm writing up a security document and it would be great if programmers in other languages than PHP could chime in on (perhaps the default) way sessions are passed by URL in their language's default session handler.
eg. PHPSESSION=token in PHP
Oh, and if yes does it also use cookies?
I have an asp.net site. Its a mixture of web forms and MVC2.
I have this on 2 different servers which I get to via different urls.
On one server authentication works fine via all browsers (IE 8, FF 3.6, Chrome)
On the other IE 8 fails, it doesn't send back the cookie on the request to the page after authenticating.
Using Fiddler I have seen that both sites attempt to set the cookie, in the response from the login page.
Response Header I see from both servers
Set-Cookie: DemandLaunch=CCA4...E79C2D1; path=/; HttpOnly
Both sites are in the internet zone of IE.
I'm at a loose for what to check now.
I also have a page that sets a cookie via c# code and that cookie fails in IE as well.
The IE issue is not on a single computer either. I see this failure on 4 different computers Internet Explorer.
My urls which I should have included were:
beta.[site].com - works
beta_[company].[site].com - fails
How to create Uniue Token with properties like expiration time,
Any standars method provided by Microsoft,
I'm trying to get a ASP.NET application to use windows authentication. I have disabled anonymous auth and enabled windows auth in IIS7. On my dev box (my workstation, localhost) I can use fiddler and see proper token is passed in through the header and I'm not prompted. Everything is working fine and I'm authenticated as my domain user.
However, on a remote server on our domain, with identical settings, I continually get prompted. We need it to automatically send the domain authentication for windows auth.
Does anything in IE need to be configured for this to happen for a remote machine on the same domain?
I have developed a web service and installed in a server suucess fully, its working fine there.
I tried to work in another server, But I had some error there in the new server.
I trying to access a network folder, Its accessible for the user which I have mentioned in the web config, But I'm having error.
in the web config
<identity impersonate="true" userName="UserName" password="password"/>
We have developed a system to allow users to access another one of our web applications by placing a token in the db and then when they redirect passing this token in the browser to the new apop and using that as an authenication method. However I am thinking that it might be better to simply place this token in the browser cookie as then the user doesnt have to physically click a link they can simply do straight to it because the token wont be in the query string anymore....
Will it add much of an overhead doing it via cookies are there any disadvantages?
I don't know if the following is possible or not but in brief, here is what I'm trying to achieve:
1. When a user requests to view a document, they click on a link (could be other) which contains an encrypted query string containing data required to retrieve the relevant document. i.e.[URL]
2. I want to ensure that if after x minutes the user goes back to their history and select the link again or re-type the same url as above that it will not request the document and redirect them to a page letting them know that the requested document "link" is no longer valid.
I don't want to rely on cookies or sessions, so thought that maybe there would be a way to add a datetime token at the end of the existing url but this needs to be done at run-time as the url is already predefined when the link is created, so I'm not sure how can I do this?
ideally, I'd like something like this [URL] where the token would contain the date & time when the link was clicked.
Once re-requested, I would decrypt the token and validate it again the server time and if it was over the x minutes defined, it would redirect me to the "link is no longer valid" page.
I have an existing asp.net mvc website that uses basic forms authentication. The site has a login page that posts back to a login action, which logs the user in via FormsAuthentication.SetAuthCookie(). I am looking to add an api to the site, as an mvc2 area, where users would be authenticated based on a token passed as an http header. This area will consist of only json actions, so redirecting the user to a login page doesn't make sense. Instead, I want the users to just pass a token along with each request. That token is mapped to each user account and the user would be authenticated automatically.
I'm struggling with where to put this logic. At this point, the best choice seems to be adding the header lookup logic and authentication to the Global.asax in the Application_AuthenticateRequest method. I want to avoid needing to redirect the user after calling FormsAuthentication.SetAuthCookie(), though. I want the login action to be transparent to them. Am I approaching this the wrong way? As a side note: Requiring a username/password for api requests is not possible, as the site has a mix of users. Some joined using OpenID while the rest joined with a username/password.
I'm using the Windows Identity Foundation (WIF) Security Token Service (STS) to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in.
Here's what occurs in my login.aspx on the STS
var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket);
if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14);
Response.Cookies.Add(cookie);
var returnUrl = Request.QueryString["ReturnUrl"];
Response.Redirect(returnUrl ?? "default.aspx");
Which was taken almost directly from existing application using normal Forms Auth.
From my web.config
<authentication mode="Forms">
<forms loginUrl="Login.aspx" protection="All" timeout="2880"
name=".STS" path="/" requireSSL="false" slidingExpiration="true"
defaultUrl="default.aspx" cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
Looking at the cookie after I sign in I can see the expires time on the cookie is set for 14 days in the future and that the cookie is NOT a session cookie. When I'm required to log back into the STS I can see that my original cookie is still there. Is there some kind of time stamp functionality that the STS embeds into the cookie that is invalidating my cookie even though as far as I know it should still be valid?
So I have an asp.net Web Application (Not Web Site) that I am trying to support profiles for anonymous users. I have a form and I want anonymous users to be able to enter their name and email only once, and have that information automatically accessible on the next load for them.
In my Web.config I have anonymous ID setup like so:
<anonymousIdentification enabled="true" cookieless="AutoDetect" />
I have my profile section setup like this:
<profile defaultProvider="SqlProvider" enabled="true" inherits="QA_Web_Tools.UserProfile">
<providers>
<clear />
<add connectionStringName="QAToolsConnectionString" name="SqlProvider"
type="System.Web.Profile.SqlProfileProvider" />
</providers>
</profile>
Finally, due to my app being a Web App and not a Web Site, I am using the profiles via this custom object:
public class UserProfile : ProfileBase
{
public static UserProfile GetUserProfile(string username)
{
return Create(username) as UserProfile;
}
public static UserProfile GetUserProfile()
{
return Create(Membership.GetUser().UserName) as UserProfile;
}
[SettingsAllowAnonymous(true)]
public string FullName
{
get { return base["FullName"] as string; }
set { base["FullName"] = value; }
}
[SettingsAllowAnonymous(true)]
public string BuildEmail
{
get { return base["BuildEmail"] as string; }
set { base["BuildEvmail"] = value; }
}
}
This code is based off of this reference. The issue is that that code does not support anonymous users, or if it does I don't know how. I can't use the GetUserProfile() method with no parameters because if the user is anonymous, Membership.GetUser() is null. I could pass in the anonymous ID token into the first GetUserProfile(string username) method but I cant' find any way to get the anonymous ID token for the current user. Does anyone know how to get this information? Google doesn't seem to be returning useful results.
I have XML like this:
<?xml version="1.0" encoding="UTF-8"?>
<viewentries timestamp="20100923T130205,90Z" toplevelentries="8903">
<viewentry position="1" unid="A4958CC88435D1A8422577A7004422E8" noteid="4DF15A" siblings="8903">
<entrydata columnnumber="0" name="$59">
<text>63722</text>
</entrydata>
<entrydata columnnumber="1" name="$70">
[Code].....
However, if I save the same xml to a file to my computer, it works without a glitch.
I've two application ASP.NET (once is Mojo Portal). I can navigate from one to other using an URL token id.
To this way, by token, I create a new session and save the relative auth cookie.
But, sometimes, the asp web application don't keep the session and put me down. When this happen I can't login until the session cookies is not deleted.
Both the two application are behind an reverse proxy.
I am using Mvc4 application while connecting using google i need to fetch the user details how to do it????
View 1 Repliesi have used "advapi32.dll" and "crypt32.dll" dlls in my application for signing the sensitive data.This is working absolutely fine when i am running my asp.net application from solution explorer(directly).But the problem arises when i am hosting this application in IIS.The application does not ask for the Pin Number of the token while signing the data.
View 1 RepliesI'm writing an ASP.net application that uses Windows Identity Foundation. My ASP.net application uses claims-based authentication with passive redirection to a security token service. This means that when a user accesses the application, they are automatically redirected to the Security Token Service where they receive a security token which identifies them to the application.
In ASP.net, security tokens are stored as cookies.
I want to have something the user can click on in my application that will delete the cookie and redirect them to the Security Token Service to get a new token. In short, make it easy to log out and log in as another user. I try to delete the token-containing cookie in code, but it persists somehow.
How do I remove the token so that the user can log in again and get a new token?
I have to generate a unique token no which will have three fields an incrementer,comp_code anddate.I have problem in generating a unique incrementer. Incrementer should be incremented by 1 like 0001,0002 etc, should be unique and based on no of record inserted.
