how to make a variable global to use in all of my cfm page?

I have a problem with the variables.

i need to use a variable  " loginrecord" in all of my cfm pages, its created in my login.cfm and the value of this needed in other page and maybe i need to change it .

in ASP simply we can use SESSION to make a variable global , is there any way in coldfusion ?

also in ASP we have a command SESSION.SESSIONID ,  so return the unique number from browser and we can se it as a security check for each one of people login to our site and each one is seperate random and unique number , is there any similar in coldfusion ?

Thanks

Alireza

Session.loginrecord will make the variable available to all the CFM pages  visited during the session.

ColdFusion has session.sessionID, too.

You can also use session variables in ColdFusion.

You just set a request variable, not a session variable.

<cfset session.foo = "I am a session variable, and will be available on every page viewed by this user, or any program called by these pages, until the session expires">

<cfset request.foo = "I am a request variable, and will be available in all programs called by this current page request.">

<cfset application.foo = "I am an application variable, and will be available on every page within this application viewed by any user, or any program called by these pages, until the application expires">

<cfset server.foo = "I am a server variable, and will be available on every page viewed by any user or any program called by these pages, anywhere on the server">

I would strongly recommend you spend some time reading the documentation, which is very well written and all online.
