/*****
|

|

Issues with the current *_proxy implementation in Node-RED:
|
||||
* no_proxy should not be case-sensitive
|
||||
* i.e. if no_proxy contains "example.com", then "example.com" and "EXAMPLE.COM" should both be excluded
|
||||
* no_proxy with protocols that have a default port are not considered
|
||||
* i.e. if no_proxy contains "example.com:443", then "https://example.com" should be excluded
|
||||
* i.e. if no_proxy contains "example.com:80", then "http://example.com" should be excluded
|
||||
* i.e. if no_proxy contains "example.com:1880", then "mqtt://example.com" should be excluded
|
||||
* Does not consider NPM proxy configuration at all
|
||||
* i.e. if npm_config_proxy is set, then it should be used
|
||||
* i.e. if npm_config_https_proxy is set, then it should be used
|
||||
* i.e. if npm_config_http_proxy is set, then it should be used
|
||||
* i.e. if npm_config_no_proxy is set, then it should be used
|
||||
* Doesn't consider https_proxy or HTTPS_PROXY
|
||||
* i.e. if https_proxy is set, then it should be used
|
||||
* i.e. if HTTPS_PROXY is set, then it should be used
|
||||
* i.e. incorrectly uses HTTP_PROXY 'http://http-proxy' when the url is 'https://example'
|
||||
* Incorrectly prioritises HTTP_PROXY over http_proxy. HTTP_PROXY is not always supported or recommended
|
||||
* i.e. if HTTP_PROXY and http_proxy are both set, then http_proxy should be used
|
||||
* Use lowercase form. HTTP_PROXY is not always supported or recommended
|
||||
* doesn't consider all_proxy or ALL_PROXY
|
||||
* i.e. if all_proxy is set, then it should be used
|
||||
* i.e. if ALL_PROXY is set, then it should be used
|
||||
*
|
||||
*
|
||||
This implementation is based on the following sources:
|
||||
* https://about.gitlab.com/blog/2021/01/27/we-need-to-talk-no-proxy/ (GitLab)
|
||||
* https://www.npmjs.com/package/proxy-from-env (MIT License)
|
||||
|
||||
This implementation proposal follows the following rules:
|
||||
* Support the following PROTOCOL_proxys
|
||||
* i.e. http_proxy, https_proxy, mqtt_proxy, ws_proxy, wss_proxy, mqtt_proxy, mqtts_proxy
|
||||
* Support all_proxy
|
||||
* i.e. if all_proxy is set, then all URLs will be proxied
