This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and SOCKS5. To enable its functionality, either install PySocks or install this module with the ``socks`` extra. The SOCKS implementation supports the full range of urllib3 features. It also supports the following SOCKS features: - SOCKS4A (``proxy_url='socks4a://...``) - SOCKS4 (``proxy_url='socks4://...``) - SOCKS5 with remote DNS (``proxy_url='socks5h://...``) - SOCKS5 with local DNS (``proxy_url='socks5://...``) - Usernames and passwords for the SOCKS proxy .. note:: It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in your ``proxy_url`` to ensure that DNS resolution is done from the remote server instead of client-side when connecting to a domain name. SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5 supports IPv4, IPv6, and domain names. When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url`` will be sent as the ``userid`` section of the SOCKS request:: proxy_url="socks4a://<userid>@proxy-host" When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion of the ``proxy_url`` will be sent as the username/password to authenticate with the proxy:: proxy_url="socks5h://<username>:<password>@proxy-host" � )�absolute_importN� )�DependencyWarningz�SOCKS support in urllib3 requires the installation of optional dependencies: specifically, PySocks.
