Web Forms :: Check To See If A Page Was Reached Through The Browser Back Button?
Feb 24, 2011
I have an application that posts to a form on a different page, on a different site. Everything works fine unless the user presses the back button.The way it'ssetup now, if th euser forgets their pin, they click alink which takes them to a popup window. The enter their info and then they're sent a new pin. Fine.However, I'm trying to account for all possible scenarios. What if the user forgets their pin, is taken to this other page, and then decides they remembered their pina nd presses the back button. They'll need to reload in order to be able to try to post again, otherwise the session variables I'm using to log them in won't reset (I reset some in the page load event).Is there anyway to detect whether the page was arrived at via the browser back button so that I can reload it?

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"); } }
In the page there are two links. When i click the first link it opens a window in a new page. I do this by using the above code.

How clicking back button is opening the link in the page. I am using c# .net 2005.

Not sure if i'm posting in the right forum, if not, please move it...i have the following issue... I want to "disable" browser's back button. Seems it's not possible, but using cache.setcacheability and timing it, kinda disables the option of navigating back. I need this because in some pages of my webpage, i keep values in a Session variable so when a page loads, i need to check that variable, and, if navigating back, cant do that. I also "set cache to false" because if someone closes session, and i allow cache, someone else could handtype a url in that same pc and see the page without login (though if he/she tries to navigate through it will be kicked out because when loading a new page, i'll know that he/she is not logged) but i dont want to allow even that,
that's why cache is disabled. The problem is that loading over and over again my masterpage (header, footer, menu and stuff) is going to slow down the webpage, because every time there's a request, the page has to be sent again completely. So, is there something like a "mix" mode where i can allow cache just for a few things? If not, what's the best practice to achieve both things i'm trying: speed and security?
After user has logged out i am redirecting user to home.aspx and from here i do not want user to be able to go back using browser back button.. How can i do it? I used this code in javascript :
My problem is when I logout from my website, the logout button redirects to login page , and then if I click BACK button in browser, I can go back to my website. I do not want that.
What I am actually trying to make is like at mail.yahoo.com or at mail.google.com after sucessful logout user cannot view the account.
I would like to make the same functionality for my application.

I am trying to build a form that will not change the URL in the users browser, and will not allow the user to press the browser back button. Is there something I can do to accomplish this?
I have a Deafult.aspx page with a form and a button. The form consists of a drop down list and a radio button list. When I click the button I submit the form to a different page, search.aspx. When I click the back button in the browser. Somehow the radio button list values stay the same as when I last clicked them (not any special configuration by my side), and the drop down list gets back to its default value. My radio button list has a on select event that changes the values of the drop down list. The problem is, as I mentioned, the radio button list keeps its former value when I submitted the page, and the dropDownList doesn't. So they are incoherent.
How do I make them both get back to their default values? (as this is no postback... right?) or how do I keep their former values. FYI, the problem doesn't occur in internet explorer. In chrome this happens. And in fire fox, it just gets back the dropdownlist is ok, but the radio button list's default selected index isn't even selected.
I am inserting and updating the image from html file upload to my gridview / insertion goes fine , but when i update the image by clicking on edit using onselectedindexchanged event of gridview, I fetch the image then change it with other image, with this simultaneously i rebind the gridview, in the beck-end everything goes fine it updates and replaces the image but in gridview it won't show after updated. I am using postbacktrigger on my submit button, but gridview won't refreshes, until and unless i click on address bar and press ENTER , or until i won't press CTRL+F5 to clear the browser cache.
