From 8459ec0ec8321a3a4e153f31398e1fe0a9306885 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Tue, 24 Apr 2018 20:32:47 +0200 Subject: [PATCH] luci-base: add simple CORS handling to luci.dispatcher Support a new boolean property `cors` which - if set to true - causes the dispatcher to positively answer CORS OPTIONS requests after authentication without actually running the dispatching target.
