You can also use session variables in ColdFusion.
i use it but not working
i set it in application.cfm
but when i change the value in other page, ( like index.cfm ) i can not retrive it in other page ( like clients.cfm )

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.

In addition to Dave's comments, if you are writing a new app, consider using Application.cfc instead of Application.cfm. In the long run it will make things simpler.
Thanks man , really i am new in coldfusion and i migrate form ASP and .NET , I have some book and also DVDs but its take time and many thing different between ASP and coldfusion.
the reason at the moment i stock with this command is i need to have login information available in all the pages to check the security. the good point i had in ASP is SESSION.SESSIONID , it make a unique number base on browser and i can check it if user loged in or no , or if loged in is the same user or other user . i couldnt find same command in coldfusion , and now i use <cflogin> but if i can find the way to have a browser session it help me in other part of my program.
i start coldfusion new ( near a month ) i have some book and Lynda DVDs, also online sources , and in this priod i re developed one of my program from ASP to coldfusion and its work. i am happy of this and help me to develop better and faster . in compare the coldfusion developed one realy is 40% original development in size and 50% faster . i have good background of ASP in last 8 years include MCSD and developed many program for a small and big companies. but i wanna to continue with coldfusion because i found it more helpfull than ASP specialy in FLASH development .
BTW thanks for your help

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 ?
Session.loginrecord will make the variable available to all the CFM pages visited during the session.
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 ?
ColdFusion has session.sessionID, too.
