Restrict my page from unauthorized users

Hello...
I am tried to restrict unauthorized user on finance.aspx page. It is working but not what I expect. When I click on finance link it redirect to me on login page. But when I already logged in and I click on finance link again it automatically redirect to me on login page that I don't want. What should I do that when user is logged in then user can we finance page otherwise if user should redirect to login page.

Code:

xml version="1.0"?>
<configuration>
  <connectionStrings>
  <add name="Employee_table" connectionString="Data Source=MCNDESKTOP10\SQLEXPRESS;Initial Catalog=MCN_Office;Integrated Security=True" providerName="System.Data.SqlClient" />
connectionStrings>
<location path="Finance.aspx">
<system.web>
<authorization>
<deny users="?"/>
<allow users="*"/>
