urllib3 is a Windows development tool for Python programmers. It allows you to send HTTP requests and receive responses from remote servers. There is support for the SSL/TLS account verification.

Overview

Using this software developers can create multiple HTTP clients. Instruments for maintaining a pool of connections to each host to reduce the number of required TCP tunnels are provided.

You are able to upload files with multipart encoding. This feature is intended for interacting with various popular web applications. The library can be used safely in multithreaded programs as well.

Response processing

There are tools for dealing with HTTP redirects. Users can handle network errors and other unexpected events.

Supported encoding technologies include gzip, deflate, brotli and zstd. Applying these compression algorithms can help you reduce the size of HTTP responses and improve the overall performance.

The library is actively maintained by the community. Bug fixes and other improvements are released regularly.
