Hi, After reading the documentation about security from phpsec.org, i see that 2 "schools" exist (dispatch method or include method). I do not see any huge difference between them. I would like to know what is the most suitable method to centralize security in 1 single file. thx. Alain ------------------------------------ Windows XP SP2 PostgreSQL 8.1.4 Apache 2.0.58 PHP 5
