Another efficient way on every page.. protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); string strDisAbleBackButton; strDisAbleBackButton =  
; strDisAbleBackButton += window.history.forward(1);
; strDisAbleBackButton += 
 ; ClientScript.RegisterClientScriptBlock(this.Page.GetType() clientScript strDisAbleBackButton); }

Response.CacheControl = no-cache; Response.AddHeader(Pragmano-cache); Response.Expires = -1; This will make the browser go to the server everytime the back button is clicked (for that particular page) and prevent any caching of the pages

Hi To meet your requirement there is need to add two page login.aspx and logout.aspx. Write the code eg. Response.Redirect(logout.aspx) on logout button that redirect you to Logout.aspx page.On logout.aspx page write this code. protected void Page_Load( object sender EventArgs e) { StringBuilder sb = new StringBuilder (); sb.Append(   ); sb.Append( top.location='Login.aspx'; ); // sb.Append(   ); Page.RegisterClientScriptBlock( disable  sb.ToString()); } when ever you redirect on logout.aspx page the above code at once redirects to login page and at seems that you are always on login page.
