== Global configuration

Global configuration files can be obtained from the following URLs (where ProgramCode is a value from the above table):

• http://us.patch.battle.net:1119/(ProgramCode)/cdns - table of domains and paths containing game data, per region
• http://us.patch.battle.net:1119/(ProgramCode)/versions - table of current game versions and CDN configs per region

== Configuration file format

All global configuration files share the same table format. Here is an example of a /cdns file:
