I have the following code in JSP:
<%
if(session.getAttribute(Username) == null || session.getAttribute(Username) == _INVALID_)
{
response.sendRedirect(LoginPage.html);
}
%>
<form>
<input type=button value=Change Account Details onClick=location.href='ChangeDetails.jsp'>
<br></br>
<input type=button value=Add Customers onClick=location.href='AddCustomers.jsp'>
<br></br>
<input type=button value=Manage Flights onClick=location.href='ManageFlights.jsp'>
<br></br>
<input type=button value=Book Flights onClick=location.href='BookFlights.jsp'>
<br></br>
<input type=button value=Log Out onClick=location.href='LoginPage.html'>
</form>
When the user clicks on the log out button, I want to redirect him to the log-in page and kill the current session. I have succeeded in the redirection part but I do not know how to kill the session. How can this be done please?
