I’m writing a dissector for a protocol that has an HTTP payload that I would like to dissect, But when I call find_dissector(“http”); it returns NULL.
Are you calling this in the register routine or the register-handoff 
routine?  There's no guarantee that any given find_dissector() call 
(other than calls to a dissector you just registered in the same 
routine) will succeed in a register routine, because there's no 
guarantee of the order in which register routines are called.  However, 
no register-handoff routines are called until all the register routines 
are called.
