user login and access + headers already sent

Hello mates, I'm developing a user registration and access level system.... And I wonder... Is there any way to avoid to put code in every header page? Because, almost every page contains javascript, so almost every page cotains <html> tags... And its annoying to look at this: Warning: session_start(): Cannot send session cache limiter - headers already sent So, I'm wondering, is there any other way to avoid put code in every page? or... another way to avoid that kind of error. Thank you. _________________________________________________________________ Got a cool Hotmail story? Tell us now http://clk.atdmt.com/UKM/go/195013117/direct/01/
