Cross origin request throws me this error: Access to XMLHttpRequest at 'http://api.indexpodnikatela.sk/fulltext' from origin 'https://www.indexpodnikatela.sk' has been blocked by CORS policy: hladaj?q=datas:1
Request header field x-firelogger is not allowed by Access-Control-Allow-Headers in preflight response.
POST https://api.indexpodnikatela.sk/fulltext net::ERR_FAILED
Is it necessary to send this custom x-firelogger header? Or how to fix it. I have access to the server but what if I will not have access?
