From 070b37906ce926b1fe1a827afe395d95d8e88706 Mon Sep 17 00:00:00 2001 From: Ammar Bandukwala Date: Wed, 10 Sep 2025 12:56:22 -0500 Subject: [PATCH 01/11] feat: add --server mode for standalone proxy operation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements a new --server flag that allows httpjail to run as a standalone HTTP/HTTPS proxy server without executing any commands. This enables use cases where httpjail acts as a persistent proxy service that applications can connect to.
