HTTP/2 [2] and HTTP/3 instead use a binary protocol, where headers are encoded in a single HEADERS and zero or more CONTINUATION frames using HPACK [3] (HTTP/2) or QPACK (HTTP/3), which both provide efficient header compression.

Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. [2] Nodes can have event handlers (also known as event listeners) attached to them. Once an event is triggered, the event handlers get executed. [3]
Requests is an HTTP client library for the Python programming language. [2] [3] Requests is one of the most downloaded Python libraries, [2] with over 300 million monthly downloads.
