type Config struct {
	// HTTPProxy represents the value of the HTTP_PROXY or
	// http_proxy environment variable. It will be used as the proxy
	// URL for HTTP requests and HTTPS requests unless overridden by
	// HTTPSProxy or NoProxy.
	HTTPProxy string

	// HTTPSProxy represents the HTTPS_PROXY or https_proxy
	// environment variable. It will be used as the proxy URL for
	// HTTPS requests unless overridden by NoProxy.
	HTTPSProxy string

	// NoProxy represents the NO_PROXY or no_proxy environment
	// variable. It specifies URLs that should be excluded from
	// proxying as a comma-separated list of domain names or a
	// single asterisk (*) to indicate that no proxying should be
	// done. A domain name matches that name and all subdomains. A
	// domain name with a leading "." matches subdomains only. For
	// example "foo.com" matches "foo.com" and "bar.foo.com";
	// ".y.com" matches "x.y.com" but not "y.com".
	NoProxy string

	// CGI holds whether the current process is running
	// as a CGI handler (FromEnvironment infers this from the
	// presence of a REQUEST_METHOD environment variable).
	// When this is set, ProxyForURL will return an error
	// when HTTPProxy applies, because a client could be
	// setting HTTP_PROXY maliciously. See https://golang.org/s/cgihttpproxy.
	CGI bool
