ASP.NET: Redirect to User's homepage - c#

Is this possible? i have an exit button on my web application, originally, my client request that once they click the exit button, it should CLOSE the tab or the browser itself but afaik that's impossible since the web aplication can be opened via link in an email (outlook,yahoomail etc) via tag, so I suggested this alternative to simply just redirect to the Home (of the user, not the web app). the problem how to Redirect to USER's home page. TIA

if (window.home){
window.home();
}else{
window.location='about:home';
}
Something like that would be my guess.
window.home() reference.

There is no way to detect user's existing settings for a home page. This is a security issue. You can always, however, close the browser window after the user is finished using your application.
JS: window.close();

Not sure that would be advisable (even if it were possible), as users can have multiple homepages. Usually, web applications have a log-out button which would log the user out and return to the application's main page (probably showing a log-in form).

c# web browser control new register

I created a program in c# with webbrowser control that opens a web site and the user will be automatically logged in. That works. However the user should also browse through different web site sections and that's where I get a problem. There is a button on one page "print preview" and what it does in "normal browser" (IE or Mozilla) it opens a new tab and shows the contents. In my program it opens Internet Explorer (it is the default browser) and shows me login page again. Can anyone explain how to open a new tab in my webbrowser control (or new window) and pass login data.
Thank you.
It can't be done the way you are trying to do it. There is no concept of tabs in the web browser control. You can verify this by loading up an html page that makes calls to window.open() in javascript. If that call is made it will just launch an instance of IE that navigates to that particular URL.
Your best bet is to have multiple web browser controls and pass data between them. Either that or use HttpWebRequest.
Although, depending on what you are trying to do you may want to automate IE instead.

Hide URL in ASP.NET application

I am developing an ASP.NET application. But i would like to hide the URL so user don't know on which page he or she standing. Is their any solution?
Use Server.Transfer . It doesn't change the URL.
Server.Transfer happens without the browser knowing anything, the browser request a page, but the server returns the content of another.
Server.Transfer() should be used when:
we don't need to show the real URL where we redirected the request
in the users Web Browser
we want to transfer current page request to another .aspx page on the
same server
we want to preserve server resources and avoid the unnecessary
roundtrips to the server
we want to preserve Query String and Form Variables (optionally)
There is no solution unless you can force the user to browse only from a restricted environment in which you can control what software is installed or run. Even if you force the user to use a specific browser, they could use a tool like Fiddler to see what URLs they are going to.

Do not maintain session

when i can close the logged in tab then it should ask for login page in next tab
please help me guys how to achieve this
thanks
You need to logged out the user when page is closing.
You can use onbeforeunload event to manually logged out the active user.
Have a look at this article about Save Changes on Close of Browser or When Exiting the Page
Login cookie is shared in same browser tabs (sometimes even in same type of browser).
In other words, if you login in a tab in IE, you do not have to login in different tabs. Login cookie is still valid, and you are automatically login.
However, if you open same page in FireFox or Chrome, you'll still have to login even if you have logged-in in IE.
Updated: Please do not ask user to re-login if a tab is closed and reopen in different tab (in same browser). Even banking websites won't do that. (Of course, user'll need to relogin if the browser is closed.)

How do I prevent returning to my site without login after closing tab with x?

I have a logout button on my site that triggers
FormsAuthentication.SignOut()
forcing the need to login again even if one uses the back button on the browser or copy/pastes the URL. However if one closes the tab by the x button of the browser and there's another tab still open, if they copy/paste the URL the page will reopen without logging in. This is a serious security problem. If the browser closed completely by closing all tabs that doesn't happen. How can I prevent returning to the URL after closing the tab even if the browser hasen't been closed completely? Is there a way of catching a javascript OnClose event that will trigger FormsAuthentication.SignOut()? I'm working in asp.net c#.
That's a browser session problem.
A browser session (in fact, the cookie which hold the session id is deleted when the browser is closed) ends only when the browser is closed. It's why you are not logout when you close only one tab without closing the whole browser.
There's no reason to logout the user when he only close a tab. This behavior is not standard on the web and users can be disoriented if you do that.
But nevermind, if you want to do that, you can write a few javascript that drop a popup to warn the user he must logout before leaving. To do that use the unload or onbeforeunload event.
Look at here to see examples :
How to create popup window when browser close
You may use javascript on window onbeforeunload event to make a call to your website and log out the user.
Wait, the user has two tabs open on your site and they click "Logout" in the one, but not in the other? Well, then they haven't really logged out - the session is still active. I see how that can be a problem. But it is not a SECURITY problem, it's just the same user that remains logged in.
Anyway, you can create, for instance, a new session variable that you fill with a value whenever the user logs in, and that you delete when the user logs out. Then in every Page_Load, check this variable, and redirect to the login page if it doesn't exist.
Might be a bit of overkill, but it's all server side and you won't need Javascript to do it.

single sign off

I found out an issue at my client's site regarding single sign off. for ease of use, i keep the client site name simple.
We developed site1.com using ektron 8.2sp2 framework and when you log into www.site1.com, you can go into "My Page" link, which takes you to www.site2.site1.com, which is a single sign-on.
This page has a log out button, when clicked, it logs off the user from www.site2.site1.com and you have a 'home' link, which takes you to www.site1.com, to log off from there too.
But, if the user just logs off from www.site2.site1.com and closes the browser, and reopens the browser to go to www.site1.com, it takes the user to the login page of www.site2.site1.com
I am trying to figure out the best way to log off the user from www.site1.com also, when the user logs off from www.site2.site1.com
I dont have access to the source files for www.site2.site1.com So, could some one help me how i can redirect the user to logoff from www.site1.com ?
This happens only in IE 8 and Firefox 3.6 but chrome behaves wonderfully.
Thanks in advance.
i guess, the answer to this is FormsAuthentication.SignOut(); will take care of it.
