    Description

      New protocol was introduced in Zabbix 1.4, but server and proxy continued to poll passive items using old protocol and all Zabbix components continue to receive plain text messages for compatibility of newer versions with pre-1.4 agents.

      It turns out (ZBX-11528) that zabbix_get has been using new protocol to poll passive items and since no one has ever complained about that, it is reasonable to make headers mandatory. Particularly, to fix ZBX-10191 which affects passive items, remote commands and can be used to attack server/proxy trappers.
