"""
|

This module contains provisional support for SOCKS proxies from within
|
||||
urllib3. This module supports SOCKS4 (specifically the SOCKS4A variant) and
|
||||
urllib3. 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:
|
||||
|
||||
- SOCKS4
|
||||
- SOCKS4a
|
||||
- SOCKS5
|
||||
- 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
|
||||
|
||||
Known Limitations:
|
||||
.. 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"
|
||||
|
||||
- Currently PySocks does not support contacting remote websites via literal
|
||||
IPv6 addresses. Any such connection attempt will fail. You must use a domain
|
||||
name.
|
||||
- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any
|
||||
such connection attempt will fail.
