I'm building an app which is subscription based, users can login to a website an use it as they. I would also like them to have the option to work with it outside of the browser and even offline. The app itself is not dependent on online resources, only the authentication is done via forms authentication. What would be the best way for me to make offline authentication possible?

Is there a way change the settings of the web broser to "Work Offline Mode" ? or the only way of doing it is to install activeX that doing so?

I am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file.The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control.Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly.

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 installed my asp.net application on server (Windows Server 2003, Standard Edition, SP2)
I already set:
1. In ASP.NET Configuration Setting: I set Authentication to None.
2. Check Enable anonymmous access.
3. Uncheck Integrated Windows Authentication.
But the brower always show Authentication Required Dialog.
If I ignore this.
It show this error:
Access is denied.
Description:
An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL.
Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.
This has been a nagging issue for some time, but very sporadic and difficult to isolate.
From time to time, browsers that have authenticated on a web application, have been open for a while, have logged in and out of the same web application multiple times, have multiple tabs, are pretty much any browser (Chrome, IE, Firefox, Safari), and seemingly at random, lose their ability to retain an AuthCookie after being set and followed by a redirect. Closing the browser and starting a new session resolves the issue, as does opening up a different browser and attempting to authenticate.
Our team uses forms authentication for all of our websites and web application. This is a pretty typical setup where a login form is displayed, the user enters credentials and a cookie is set on the click event of the postback, then a redirect occurs to the same page where the cookie is then referenced and used to complete authentication.
In this situation
FormsAuthentication.FormsCookieName = ".WebAuth"
Within Event:
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1, Username, DateTime.Now, DateTime.Now.AddMinutes(SessionTimeout), false, Username); HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(authTicket));
Response.Cookies.Add(faCookie);
Response.Redirect(Request.RawUrl, true);
After the redirect, on PreInit:
HttpCookie authCookie = Request.Cookies[cookieName];
At this point, the authCookie variable is typically not null, but in these isolated circumstances that I've outlined above, the cookie comes back null after the redirect.
This happens very randomly, sometimes weeks before affecting one of our developers. As I said, restarting the browser resolves the issue.
Today I had it happen on our dev server while using Chrome. I had logged into the application, allowed the application to session timeout, and then attempted to login again. The attempted login then failed to set the cookie. I remotely attached Visual Studio to the process on the server to begin debugging. The entire time I could step through my code, even deploy new code versions to the server with updates, restart the app, restart IIS on the server, attach and reattach to the project, and the issue persisted in Chrome. In Firefox, I was able to authenticate without issue.
From Chrome, the login would validate, attempt to set a Response Cookie as outlined above. Prior to redirect, I could see the properly set Response Cookie, as well as its counterpart in the Request Cookies. However, on each redirect after a seemingly successful login, the Response and Request Cookie are gone.
I enabled Trace on the application to view the cookie collection:
There is a .WebAuth in the Request Cookies Collection, as well as ASP.NET_SessionId and several ASPSESSIONIDxxxxxxxx, but when the page loads, only the ASP.NET_SessionId and ASPSESSIONIDxxxxxxxx cookies are available in the Request.Cookies scope, no sign of the .WebAuth. However, in the page's Trace information after render, there multiple .WebAuth cookies listed, it is just that the page seems to have no access to them.
Primarily, on a working version after authentication there is both a .WebAuth Response and Request Cookie in the page's Trace info. But on a non functioning browser window, the Response Cookie is absent.
Has anyone else had any experience with this? It is such a nagging issue, and so sporadic, but I would love to be able to resolve it. My concern is that it may be affecting users and we would have no knowledge since the description of the issue is so convoluted.
When i disable cookie at browser level will 'Form authentication' still work ?.If not,What is the alternative that enables the 'From Authentication' ?

Once I have logged in I can see the website fine. My problem is that every time I open a new IE browser I have to re-enter my username and password. I have heard about thew double hop issue, is this what it could be. If so how many ip fix this. Any ideas how i can stop this box showing up each time?

View 1 RepliesWhile having a file App_Offline.htm takes the entire application offline from the web server, is it possible to just take a particular or certain particular pages offline?
E.g. Default2.aspx, Default3.html, Default4.htm, etc.
Such that when a user navigates to the page, a message would tell the user that the page is offline / redirect the user to an alternative page?

I know about the app_offline.htm file. But using this "trick" I would need to put a file per web application in the server, right?

So the question is: Is there a better way of doing this?
