Tim Leung	ddb240293a	Add support for no_proxy and case insensitive env variables (#9372) ... ### Changes proposed in this PR - Add support for the `no_proxy` and `NO_PROXY` environment variables - Internally rely on urllib's [`proxy_bypass_environment`](bdb941be42/Lib/urllib/request.py (L2519)) - Extract env variables using urllib's `getproxies`/[`getproxies_environment`](bdb941be42/Lib/urllib/request.py (L2488)) which supports lowercase + uppercase, preferring lowercase, except for `HTTP_PROXY` in a CGI environment This does contain behaviour changes for consumers so making sure these are called out: - `no_proxy`/`NO_PROXY` is now respected - lowercase `https_proxy` is now allowed and taken over `HTTPS_PROXY` Related to #9306 which also uses `ProxyAgent` Signed-off-by: Timothy Leung tim95@hotmail.co.uk	2021-02-26 17:37:57 +00:00
Marcus	e385c8b473	Don't apply the IP range blacklist to proxy connections (#9084) ... It is expected that the proxy would be on a private IP address so the configured proxy should be connected to regardless of the IP range blacklist.	2021-01-12 12:20:30 -05:00
Richard van der Hoff	1cb84c6486	Support for routing outbound HTTP requests via a proxy (#6239) ... The `http_proxy` and `HTTPS_PROXY` env vars can be set to a `host[:port]` value which should point to a proxy. The address of the proxy should be excluded from IP blacklists such as the `url_preview_ip_range_blacklist`. The proxy will then be used for * push * url previews * phone-home stats * recaptcha validation * CAS auth validation It will *not* be used for: * Application Services * Identity servers * Outbound federation * In worker configurations, connections from workers to masters Fixes #4198.	2019-11-01 14:07:44 +00:00
