aiodns
DNS resolver for asyncio.

asyncio
The library for writing single-threaded concurrent code using
coroutines, multiplexing I/O access over sockets and other
resources, running network clients and servers, and other
related primitives.
Reference implementation of :pep:`3156`
https://pypi.python.org/pypi/asyncio/
Brotli
Brotli is a generic-purpose lossless compression algorithm that
compresses data using a combination of a modern variant
of the LZ77 algorithm, Huffman coding and second order context modeling,
with a compression ratio comparable to the best currently available
general-purpose compression methods. It is similar in speed with deflate
but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined :rfc:`7932`
https://pypi.org/project/Brotli/
callable
Any object that can be called. Use :func:`callable` to check
that.
chardet
The Universal Character Encoding Detector
https://pypi.python.org/pypi/chardet/
cchardet
cChardet is high speed universal character encoding detector -
binding to charsetdetect.
https://pypi.python.org/pypi/cchardet/
gunicorn
Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for
UNIX.

IDNA
An Internationalized Domain Name in Applications (IDNA) is an
industry standard for encoding Internet Domain Names that contain in
whole or in part, in a language-specific script or alphabet,
such as Arabic, Chinese, Cyrillic, Tamil, Hebrew or the Latin
alphabet-based characters with diacritics or ligatures, such as
French. These writing systems are encoded by computers in
multi-byte Unicode. Internationalized domain names are stored
in the Domain Name System as ASCII strings using Punycode
transcription.
keep-alive
A technique for communicating between HTTP client and server
when connection is not closed after sending response but kept
open for sending next request through the same socket.
It makes communication faster by getting rid of connection
establishment for every request.
nginx
Nginx [engine x] is an HTTP and reverse proxy server, a mail
proxy server, and a generic TCP/UDP proxy server.
https://nginx.org/en/
percent-encoding
A mechanism for encoding information in a Uniform Resource
Locator (URL) if URL parts don't fit in safe characters space.
requests
Currently the most popular synchronous library to make
HTTP requests in Python.
https://requests.readthedocs.io
requoting
Applying :term:`percent-encoding` to non-safe symbols and decode
percent encoded safe symbols back.
According to :rfc:`3986` allowed path symbols are::
allowed = unreserved / pct-encoded / sub-delims
/ ":" / "@" / "/"
pct-encoded = "%" HEXDIG HEXDIG
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
sub-delims = "!" / "$" / "&" / "'" / "(" / ")"
/ "*" / "+" / "," / ";" / "="
resource
A concept reflects the HTTP **path**, every resource corresponds
to *URI*.
May have a unique name.
Contains :term:`route`\'s for different HTTP methods.
route
A part of :term:`resource`, resource's *path* coupled with HTTP method.
web-handler
An endpoint that returns HTTP response.
websocket
A protocol providing full-duplex communication channels over a
single TCP connection. The WebSocket protocol was standardized
by the IETF as :rfc:`6455`
yarl
A library for operating with URL objects.
