@g0untlet you could try the reverse proxy config option - i.e. if you're fetching https://example.com/index.js set up a reverse proxy config:

P:/local-index.js:https://example.com/index.js

...then point your files to /local-index.js. Depending on the remote server you might still have issues fetching that file from behind a reverse proxy though 🤷

Sorry for bothering again but I get the following error on docker compose up:
httpd: config error 'P:/proxy.htlm:http://192.168.178.167/report/xxx.html' in 'httpd.conf'
