Handling browser(&lt;--) and (--&gt;) buttons K V Sekhar5-Sep-08 21:07 K V Sekhar 5-Sep-08 21:07  Hi all, I wants not allow user to revisit the previous pages once he logged out. I am using master page, in that i placed a logout linkbutton. When user clicks on logout button, i am redirecting user to loginpage.aspx. In the Design of loginpage.aspx i wrote the following javascript to prevent user to navigate through browser -> & <- buttons. LoginPage.aspx: <%@ Page Language="C#" MasterPageFile="~/ProxyAds.master" AutoEventWireup="true" CodeFile="LoginPage.aspx.cs" Inherits="LoginPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="server"> <script language="javascript" type= "text/javascript"> if (window.history) { window.history.forward(1); } </script> <div id="home"> //Login Controls here.... </div> </asp:Content> ......................... But its not working. any thing i am doing wrong ? please suggest me. thanks in advance. Re: Handling browser(&lt;--) and (--&gt;) buttons balaji.t5-Sep-08 23:41 balaji.t 5-Sep-08 23:41  hi, try giving like this window.history.forward(-1) T.Balaji Re: Handling browser(&lt;--) and (--&gt;) buttons K V Sekhar6-Sep-08 1:59 K V Sekhar 6-Sep-08 1:59  Thanks balaji, thanks for ur suggestion. There is nothing wrong in that logic, its woks fine.I already tested that logic by placing that on MasterPage. But the problem is it totally not allowing user to navigate through browser buttons. through out the application it is not allowing. I dont want that kind of functionality. I only wants user to not allow to visit previous pages only after he logged out from site. Is that ok place Script in LoginPage.aspx ? bcz its the home page. Please suggest me, Thanks in advance. Re: Handling browser(&lt;--) and (--&gt;) buttons Dilip H. Patel6-Sep-08 0:28 Dilip H. Patel 6-Sep-08 0:28  Hi Shekhar, Dilip Here. In such situations, why don't you use window.histoty.delete. But i am suggesting to use C# backcode to handle such situations. when user log in, you would store his userid in session. when user log out you would delete userid from session. when user passes any request (either with browser back button or giving url in addressbar), you can check in page load event whether user is loggin or not. if not than you can redirect page to login page Regards Dilip Patel Re: Handling browser(&lt;--) and (--&gt;) buttons K V Sekhar6-Sep-08 1:56 K V Sekhar 6-Sep-08 1:56  Thanks dilip, thanks for ur suggestion. I implemented that also, with this the ploblem is when user hits browser(<- & ->) buttons control, some times is not comming into PageLoad event. I checked by placing BreakPont on Pageload. May be the reason is Browser is catching the previous pages when we hit <- buttons it simply displays the page. If i put the above logic in MasterPage working fine,but the problem is it totally not allowing user to navigate through browser buttons. through out the application it is not allowing. I dont want that kind of functionality. I only wants user to not allow to visit previous pages only after he logged out from site. Is that ok place Script in LoginPage.aspx ? bcz its the home page.

Here wht m doing is , m checking login details against a database. if is a valid user then allowing to browse throuth the application. my requirement is if one user is loged in and if someother user tries to login with same user account i need to restrict the second user saying "this login is already in use". I can maintain a temp table for this , whenever a login is success i can update "isloged" field as true and we can set it false when user logs out. but how can we handle situations like if a user logs in and closes bowser close button instead of log out. if a user logs in and leaves doing nothing. pls help in resolving this, if possible write a sample code for me. thanks in advance.
