*{command}* is used to create target HTTP proxies. A target
|
|
HTTP proxy is referenced by one or more forwarding rules which
|

specify the network traffic that the proxy is responsible for
|
|
routing. The target HTTP proxy points to a URL map that defines
|
|
the rules for routing the requests. The URL map's job is to map
|
|
URLs to backend services which handle the actual requests.
