 The following table provides an inventory of environment variables that can be set to configure a proxy for use.
 
-| Environment variable | Purpose                                                                                                      |
-|----------------------|--------------------------------------------------------------------------------------------------------------|
-| `HTTP_PROXY`         | The proxy server used on HTTP requests.                                                                      |
-| `HTTPS_PROXY`        | The proxy server used on HTTPS requests.                                                                     |
-| `ALL_PROXY`          | The proxy server used for both HTTP and HTTPS requests, in case `HTTP_PROXY` or `HTTPS_PROXY` are undefined. |
-| `NO_PROXY`           | A comma-delimited list of hostnames to exclude from proxying.                                                |
-| `GATEWAY_INTERFACE`  | Set if running in a CGI environment. Example value: `CGI/1.1` |
+| Environment variable | Purpose                                                                                                     |

 Be aware of the following behaviors:
 
 - Each environment variable in the preceding table, except `GATEWAY_INTERFACE`, can alternatively be defined as lowercase. For example, `http_proxy`. The lowercase form takes precedence over the uppercase form.
 - If both `http_proxy` and `GATEWAY_INTERFACE` are undefined, `HTTP_PROXY` is used.
+- `ALL_PROXY` is considered only when either an HTTP or an HTTPS proxy is undefined.
 - Protocol-specific environment variables take precedence over `ALL_PROXY`.
 
 The proxy server URL takes the form `http[s]://[username:password@]<ip_address_or_hostname>:<port>/`, where the `username:password` combination is optional. To get the IP address or hostname, port, and credentials for your proxy server, consult your network administrator.
