How does it work
The armory works by having several people running around with an addon which saves a database of players that are targeted. This database is later sent to the server by using a small simple uploader program which you either manually or automaticly run everytime you close wow. The server parses the lua database and saves the data in a binary format. The website reads the latest version of the binary database once every 10 minutes and keeps it in memory.
