This program converts a WSGI program to an ASGI program or the other way around. It depends only on the Python standard library.

In order to be compatible with legacy web content when interpreting something like Content-Type: text/html; charset=latin1, tools need to use a particular set of aliases for encoding labels as well as some overriding rules. For example, US-ASCII and iso-8859-1 on the web are actually aliases for windows-1252, and a UTF-8 or UTF-16 BOM takes precedence over any other encoding declaration. The WHATWG Encoding standard defines all such details so that implementations do not have to reverse-engineer each other.

This module implements the Encoding standard and has encoding labels and BOM detection, but the actual implementation for encoders and decoders is Python’s.

This package provides a Python Twisted library for LDAP, which key feaatures are:

WCrypto is an implementation of the Javascript Object Signing and Encryption (JOSE) Web Standards.

The SAML Python Toolkit lets you add SAML support to your Python software.

This package provides a rate limiting extension for Starlette and Fastapi.

This middleware provides cross-origin resource sharing (CORS) support for Falcon. It allows applying a specially crafted CORS object to the incoming requests, enabling the ability to serve resources over a different origin than that of the web application.

Flask-Limiter adds rate limiting to Flask applications. Rate limits can be configured at different levels such as:

• Application wide global limits per user

• Default limits per route

• By blueprints

• By class-based views

• By individual routes

robot_detection is a python module to detect if a given HTTP User Agent is a web crawler. It uses the list of registered robots from http://www.robotstxt.org.

The marshmallow-jsonapi package provides a simple way to produce JSON:API-compliant data in any Python Web framework. It includes optional utilities to integrate with Flask. This is a forked version whose pypi name is marshmallow_jsonapi_minfork.

This module contains a pure-Python HTTP/2 header encoding (HPACK) logic for use in Python programs that implement HTTP/2.

Waitress is meant to be a production-quality pure-Python WSGI server with very acceptable performance.

This package provides a URI Normalization function with following features:

• take care of IDN domains

• always provide the URI scheme in lowercase characters

• always provide the host, if any, in lowercase characters

• only perform percent-encoding where it is essential

• always use uppercase A-through-F characters when percent-encoding

• prevent dot-segments appearing in non-relative URI paths

• for schemes that define a default authority, use an empty authority if the default is desired

• for schemes that define an empty path to be equivalent to a path of /, use /

• for schemes that define a port, use an empty port if the default is desired

• all portions of the URI must be utf-8 encoded NFC from Unicode strings

This tool provides a simple HTTP server with support for Range requests.

htmlmin2 is an HTML minifier that just works. It comes with safe defaults and easily configurable options. This variant is an updated fork of the original python-htmlmin.
