map
The map function maps a request URI to a URL on another server, allowing you to specify that a request should be serviced by another server. To load balance a given URI across multiple servers, use the map function in conjunction with the set-origin-server function. The map function looks for a certain prefix in the URI that the client is requesting. If map finds the prefix, it replaces the prefix with the mirror site prefix.
Parameters
The following table describes parameters for the map function.
