From e7a484e401c2b3300a2a4c49d16ebf073168f76b Mon Sep 17 00:00:00 2001 From: Jason Song Date: Fri, 19 Apr 2024 12:03:53 +0800 Subject: [PATCH] Avoid importing `modules/web/middleware` in `modules/session` (#30584) Related to #30375. It doesn't make sense to import `modules/web/middleware` and `modules/setting` in `modules/web/session` since the last one is more low-level. And it looks like a workaround to call `DeleteLegacySiteCookie` in `RegenerateSession`, so maybe we could reverse the importing by registering hook functions.
