WP_HTTP_Proxy::send_through_proxy() public WP 2.8.0

Determines whether the request should be sent through a proxy.

We want to keep localhost and the site URL from being sent through the proxy, because some proxies can not handle this. We also have the constant available for defining other hosts that won't be sent through the proxy.
