login session in coldfusion

[muntago Richard]

Am building login session in coldfusion.
how do i directly prevent users from accessing success.cfm page by forcing the user to login again if he does
in other words they must login to access success.cfm page.
thank

login.cfm

<cfapplication name="GetLeadApp"  
    sessionmanagement="Yes" 
    sessiontimeout=#CreateTimeSpan(0,0,45,0)#>


<cfif not isdefined("Form.Contract")> 
    <cfset Form.Contract = "No"> 
</cfif> 

<cfquery name="result" datasource="world">
SELECT * FROM user_log
WHERE username = '#Form.username#'
AND password = '#Form.password#'
</cfquery>
<cfif result.Count gt 0>
    
<cflock timeout=20 scope="Session" type="Exclusive"> 
    <cfset Session.username = '#Form.username#'> 
</cflock>
<cflocation url="success.cfm" addtoken="no">


<cfelse>
      
<font color=red><h1>Invalid Username or Password</h1></font>
</cfif>

success.cfm

<cfapplication name="GetLeadApp"  
    sessionmanagement="Yes" 
    sessiontimeout=#CreateTimeSpan(0,0,45,0)#>
