Exported Type Names

type Config (struct) Config holds configuration for HTTP proxy settings. See FromEnvironment for details. 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. 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. 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. NoProxy represents the NO_PROXY or no_proxy environment variable. It specifies a string that contains comma-separated values specifying hosts that should be excluded from proxying. Each value is represented by an IP address prefix (1.2.3.4), an IP address prefix in CIDR notation (1.2.3.4/8), a domain name, or a special DNS label (*). An IP address prefix and domain name can also include a literal port number (1.2.3.4:80). 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". A single asterisk (*) indicates that no proxying should be done. A best effort is made to parse the string and errors are ignored. ProxyFunc returns a function that determines the proxy URL to use for a given request URL. Changing the contents of cfg will not affect proxy functions created earlier. A nil URL and nil error are returned if no proxy is defined in the environment, or a proxy should not be used for the given request, as defined by NO_PROXY. As a special case, if req.URL.Host is "localhost" (with or without a port number), then a nil URL and nil error will be returned. func FromEnvironment() *Config
Exported Values
func FromEnvironment() *Config FromEnvironment returns a Config instance populated from the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions thereof). HTTPS_PROXY takes precedence over HTTP_PROXY for https requests. The environment values may be either a complete URL or a "host[:port]", in which case the "http" scheme is assumed. An error is returned if the value is a different form.
