Hello Guys!
I have problens with CORS in openlitespeed. I followed the tutorial from https://openlitespeed.org/kb/setting-up-cors-on-openlitespeed/#How_to_Enable_CORS and inserted a line "extraHeaders Access-Control-Allow-Origin *" in the /usr/local/lsws/conf/vhosts/Example/vhconf.conf but still does not work. When I try to open my web app. The app access a subdomains in the same server.

Error :
Access to XMLHttpRequest at 'https://subdomainA.xxxxxx' from origin 'https://subdomainB.zzzzz' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

My Vhost.conf

`docRoot $VH_ROOT/html/
