This question is very similar to this <a href="https://stackoverflow.com/questions/533867/whats-the-best-method-for-forcing-cache-expiration-in-asp-net">one</a>...

You need to force the cache to expire for this to work. Place the following code on your page code behind.

<pre><code>Page.Response.Cache.SetCacheability(HttpCacheability.NoCache)
</code></pre>

While i'm looking for the answer myself,
"Best Practice" is.... outdated... Just like browsers are.(Really browsers are ugly fossils)

The best/safest solution would be for browsers to implement a method/request where the user can grant the page the ability to control the interface.

Why? Because for my current project i'm building a 100% JavaScript built and controlled interface.. And back button's have no place in my project since there is no page change. (Ie bloody fast and no page-flashes because of a refresh.. Just like a real application!)

I know why the ability to "highjack" the interface isn't there, and i understand it. But atleast we should have the ability to request it from the browser! Now that would truly be "best practice" without the highjack dangers.

But browsers being browsers.. I don't expect anything exiting to happen in this regard.

blocks|key|1322413|text|我正在搜索同样的问题，我在一个网站上找到了下面的代码。想在这里分享一下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1322414|function+noBack()

I was searching for the same question and I found following code on a site. Thought to share it here:

<pre><code>function noBack()
{
 window.history.forward()
}
noBack();
window.onload = noBack;
window.onpageshow = function(evt){ if(evt.persisted) noBack(); }
window.onunload = function(){ void(0); }

However as noted by above users, this is never a good practice and should be avoided for all reasons.

blocks|key|1537476|text|如果你依赖客户端技术，它是可以被规避的。例如，可以禁用Javascript。或者用户可能会执行JS脚本来绕过您的限制。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1537477|我的猜测是，您只能通过在服务器端跟踪用户会话，并将用户/浏览器重定向(就像在Server.Transfer中那样，而不是Response.Redirect)到所需的页面。|1537478|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If you rely on client-side technology, it can be circumvented. Javascript may be disabled, for example. Or user might execute a JS script to work around your restrictions.

My guess is you can only do this by server-side tracking of the user session, and redirecting (as in Server.Transfer, not Response.Redirect) the user/browser to the required page.

Google "how ajax broke the back button" and you'll find plenty of articles on user testing and the validity of disabling the back button.

I also had the same problem, use this Java script function on head tag or in , its 100% working fine, would not let you go back.

<pre><code> &lt;script type = "text/javascript" &gt;

blocks|key|1322752|text|试试这段代码。对我很管用。它基本上是在页面加载后立即更改散列，通过在URL上添加"1“来更改最近的历史页面。所以当你点击“后退”按钮时，它每次都会重定向到同一页面。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1322753|+<script+type="text/javascript">

Try this code. Worked for me. It basically changes the hash as soon as the page loads which changes recent history page by adding "1" on URL. So when you hit back button, it redirects to same page everytime.

<pre><code> &lt;script type="text/javascript"&gt;
 var storedHash = window.location.hash;
 function changeHashOnLoad() { window.location.hash = "1";}
 window.onhashchange = function () {
 window.location.hash = storedHash;
 }
&lt;/script&gt;

&lt;body onload="changeHashOnLoad(); "&gt;

&lt;/bod&gt;

blocks|key|1537581|text|与其试图禁用浏览器的后退按钮，不如支持它。.NET+3.5可以很好地处理浏览器的后退(和前进)按钮。用谷歌搜索："Scriptmanager+EnableHistory“。您可以控制哪些用户操作会将条目添加到浏览器的历史记录(ScriptManager、->、AddHistoryPoint)中，并且每当用户单击浏览器的后退/前进按钮时，ASP.NET应用程序都会收到一个事件。这将适用于所有已知的浏览器|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1537582|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Instead of trying to disable the browser back button it's better to support it.
.NET 3.5 can very well handle the browser back (and forward) buttons. Search with Google: "Scriptmanager EnableHistory". 
You can control which user actions will add an entry to the browser's history (ScriptManager -> AddHistoryPoint) and your ASP.NET application receives an event whenever the user clicks the browser Back/Forward buttons. 
This will work for all known browsers

try these things maybe these will work for you

in login page <code>&lt;head&gt;</code> tag:

 window.history.forward();
&lt;/script&gt;

in Logout Button I did this:

<pre><code>protected void Btn_Logout_Click(object sender, EventArgs e) 
{
 connObj.Close();
 Session.Abandon();
 Session.RemoveAll();
 Session.Clear();
 HttpContext.Current.Session.Abandon();
}
</code></pre>

and on login page I have put the focus on Username textbox like this:

<pre><code>protected void Page_Load(object sender, EventArgs e)
{
 _txtUsername.Focus();
}
</code></pre>

hope this helps...

 var key = e.keyCode || e.which;
 if (key == 8 /*BACKSPACE*/ || key == 46/*DELETE*/) {
