Query Packet Manipulation

SAPP allows you to add additional fields to the query packet received through Halo’s query’s system.

Command Usage	Effect
query_add <key><value>	Add an entry to the query string or overwrites an existing query value.
query_del <index orname>	Remove an entry from the query string.
query_list	List custom query entries.

To request a query packet, simply send “query” to the server’s UDP port through a UDP socket. Each entry is separated with backslashes with the first entry and every other entry after that being a key and the second entry with every other entry after that being a value to its respective key. These packets are often used with game tracking services and automatically-generated status images.
