"Rendering" Page For The First Time After After Clicking Browser "Back" Button?
May 13, 2010
I was finally able to expire a page in both Firefox 3 and IE7, so that when the user clicks on "Back", I'll either get a message from the browser saying that it needs to connect to the server to reload the page (FF3), or simply display the "Webpage has expired" message (IE7). So both browsers retrieve it from the server.
Unfortunately, it will refresh the last copy the browser has in the cache. In my case, the last copy displays a ton of data that does not exist anymore since the process' lifecycle was already completed. I need the browser to display the webform as if it the user went there for the first time.
I believe that for all purposes, clicking "Resend" in Firefox (when hitting "Back") is the same as pressing F5 in IE7 when the "Webpage has expired" page is displayed, which is basically a page postback.
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.
I am clicking the second link in the page and navigating to another page. Now i am clicking the browser back button. Supprisingly its opening the first link.
How clicking back button is opening the link in the page. I am using c# .net 2005.
we are making an application in asp.net(visual studio 2008). In this we have made a page in which we have a submit button. on clicking on this submit button we go to next page.on this next page we have a back button.we want that when we click on this back button then the values that we have entered in the previous page is preserved(i.e displayed on the controls in which we have filled).
I am using ASP.NET, the web page is abandoning and clear session when a user click logout link but they click the back button and it is still showing the previous page. How can it prevent the previous page after logout? on Logout.aspx load im using this code
Session.Clear(); Response.Buffer = true; Response.ExpiresAbsolute = DateTime.Now.AddDays(-1D); Response.Expires = -1500; Response.CacheControl = "no-cache"; //----- Second Technique : To Stop Caching of Secure Pages. Response.Cache.SetCacheability(HttpCacheability.NoCache); FormsAuthentication.SignOut(); if (Session["UserName"] == null) { Response.Redirect("login.aspx"); } Session.Clear();
Can I save a page position in browser after clicking button or some other actions (after PostBack)
I need it on Page Change event in my DBGrid like on msdn.microsoft.com - when I change Tab C# -> C++ for example it doesn't refresh whole page and I still being on same position in browser.
From pageA, clicking a button to open pageB which display a crystal report. User can only use browser back button. How to open pageC from pageB? Can I add code in pageB close (if there is a page close event) or make back button in browser to open pageC instead of pageA?

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"); } }
I am using Ajax authentication service to login/logout users.And have 2 boxes one for logged users,another for any user.When user logged in he get loged in box,then go to another page,then press back,i have unlogged box.In Page_Load i check if (Reques.IsAuthenticated) then i change box on corresponding,in this case on Logged in box.But Page_Load is not called when i press button back(in browser) or backspace.

When I click Logout page redirect to Login page but when click to browser arrow back then it will goes back, I want to after Logout cannot going to back page...
I would like to clear sessions after hitting back button . Iuse the java script to disable back button how can i clear sessions now after hitting back button.
I use the following script
<script type="text/javascript"> function preventBack(){window.history.forward();} setTimeout("preventBack()", 0); window.onunload=function(){null}; </script>
My webapplication starts a new session at a point, where there is no reason.For the moment I even don't know, which part of code I should post.Clicking a button in the browser on the app, everything is ok for the first time.Clicking it a second time, the new session begins.
What could be the reason for this behavior? Perhaps after an answer I can better determine, what lines of code I need to show you.
