Using proxy for http requests

I must be somewhat dense today but I need to use a proxy server for ALL http requests and I can't tell if I need to use --proxy (and if so, which stanza since this is a built-in server-side test) or if I just set the environment variable http_proxy= will work.  I would prefer not to have to add it to all of my http tests individually and it's also not clear if that syntax will work for the "apache=" entries.
