how to maintain state using session variables

hi guys,
i just started working on dynamic web applns and i want to know how i can use the session variables to maintain users state.
any help is welcome

Not sure what kind of help you are looking for here. Session variables are held on the server side, you can set their values just like any other variable. When new pages are loaded to the browser, you can check the value of the session to determine the state.

ok if thats the case then i suppose i have to enable sessionmanagement in <cfapplication> tag and then include <cfapplication> tag on each page using session variable.and can i randomly generate cfid and cftokens?actually i wanted to know about cfids and cftokens.
my mistake

thanks buddy i'll take a look at it

I think you need to do some reading, any good book on CF will cover this in detail. You don't need to include the <cfapplication> tag on each page, but it does need to run on each request. You can place it in the Application.cfm file which automatically runs before any other page in your application runs. Place this file in your application's root director. Again, a good book will cover this, and it's fully explained in the documentation as well.

CFID and CFTOKEN are automatically created by the CF server when you are using the <cfapplication> tag.
