hi,

if i use http\_session\_id in http.bro and my\_script.bro  
i define  
global http\_session\_id = 0 ;  
in both the scripts.  
It says "already defined".

If i remove from one place it says "Not defined"

Can i get around this prob ? I thought global would make the variable visible to all the scripts.

thanks
