i want to protect pages from back button of the browser when my customer logout. so i use Response.AppendHeader ("Cache-Control", "no-store"); to clear the cache of my pages to make it checks session each time. however, i also find that if i use some controls with autopost back and this no-cache flag will also cause problem to make the error "webpage has expired" when my users click back button when they have not logged out.
I am using the following code to ensure that the web pages in my website are not cached by the browser:
this.Response.Expires = 0;
this.Response.AppendHeader("Pragma", "no-cache");
this.Response.Cache.SetNoStore();
This is working fine & the browser displays a page with the message, "Warning. This page has expired....". Is there any way I can display a custom page instead of the default page shown by the browser?
i designed a shopping cart application and i implemet some script to prevent back button. If i hit back button i am getting the error as webpage expired. If i refresh again the same page is getting displayed. What i need is i would like to be the user in the same page if he hit the back button. In some cases if i hit back button the previous page is getting displayed and again redirectiing to the current page.
My customer has a website that is unsuitable for children. Anyone under 18 is not allowed ont he site. No, it's not a porn site, it's prison related. A certain page requires the user to enter their birthdate. If they are under 18, they're redirected to another site.
He has another site written for kids who have been impacted by crime. He wants the kids redirected here, to a page that explains why they were redirected. He asked me to disable the back button at this point to keep the kids from easily going back to the original site.
I've read all the reasons why you shouldn't desable the back button, but frankly, I think this would an appropriate place to do it. I also know you really can't disable it, but I've found a number of work arounds - none of which I've gotten to work.
Is there a work around that will work?
I've thought of setting a session variable or a hidden field or an invisible label on the page that redirects the kids just before the redirect and checking the value at page load, but the code to do the checking doesn't get run unless the user hits the back button then refreshes the page. Is there a way to get code to run as soon as the back button is pressed?

I'm using 2 masterpages in my project.One master page is for login page and another one for the HomePage where user will go thro the options to reach other pages from home page..The thing is,i have "Logout" button in my home page.When i click on the logout button,the page will be redirected to "LoginPage.aspx". After redirecting to login page,when i click on browser back button,the previous page is displaying but it should not display to user since i'm doing sensitive transactions in all pages...
When we click our back button the page only returns to the previous state (un checking the check boxes one by one after each click). We would like it to go back to the previous page and remember the history of the page.

I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side string arg = this.Request.Params.Get("__EVENTTARGET"); if (arg == "Payment") { this.ProcessPayment(); } Button <asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" /> alert(group);
I have read that you can not disable the back button on page load but I can clear the cashe on page load so the back button would then be greyed out. I have read a few articles on this and I am unable to get it working. I am using MS visual web developer 2010.

I am using Html.RenderAction<CartController>(c => c.Show()); on my master Page to display the cart for all pages. The problem is when I add an item to the cart and then hit the browser back button. It shows the old cart (from Cache) until I hit the refresh button or navigate to another page.
I've tried this and it works perfectly but it disables the Cache globally for the whole page an for all pages in my site (since this Action method is used on the master page). I need to enable cache for several other partial views (action methods) for performance reasons.
I wouldn't like to use client side script with AJAX to refresh the cart (and login view) on page load - but that's the only solution I can think of right now.
