HTTP/2 Unleashes Parallel Downloads, Breaking the Connection Limit

Modern websites require access to hundreds of files simultaneously, but HTTP/1.1's six-connection limit forces sequential downloading and triggers head-of-line blocking issues that severely impact performance. HTTP/2 solves this through connection multiplexing, enabling all files to stream concurrently over a single connection. This architectural shift is crucial for improving web performance and user experience in today's asset-rich web ecosystem.
