I set some 'add_header' options in my global local.cf and could not figure out why they were not being applied. It turns out that because I am using SQL user_prefs, any add_header lines I put in local.cf are just ignored (even though I have no global or individual add_header lines configured in my sql table).
Is there any documentation that details which options that I might configure in local.cf that are overridden by user prefs simply existing? I know I can set a @GLOBAL pref with these add_header lines if I wish, and I can set them for my user, but I thought that by setting them in my local.cf they would be honored globally as well, as certain other things that are set there are honored globally. I'm not sure which are and which are not. micah
