From 14e748793e8a08d7c2130f63896074f4980204cb Mon Sep 17 00:00:00 2001 From: Matthias Endler Date: Thu, 13 Jul 2023 17:32:41 +0200 Subject: [PATCH] Cookie Support (#1146) This is a very conservative and limited implementation of cookie support. The goal is to ship an MVP, which covers 80% of the use-cases. When you run lychee with --cookie-jar cookies.json, all cookies will be stored in cookies.json, one cookie per line. This makes cookies easy to edit by hand if needed, although this is an advanced use-case and the API for the format is not guaranteed to be stable.
