XMLHttpRequest не может загрузить с другого сайта

Question

Я столкнулся эту ошибку:

XMLHttpRequest cannot load https://xyz.com/test/points?domain=test.com&id=100. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ('https://sourcerequest.com') is therefore not allowed access. 

Даже я поставил заголовок так:

headers['Access-Control-Allow-Origin'] = request.headers["HTTP_ORIGIN"] 
    headers['Access-Control-Expose-Headers'] = 'ETag' 
    headers['Access-Control-Allow-Methods'] = 'GET, POST, PATCH, PUT, DELETE, OPTIONS, HEAD' 
    headers['Access-Control-Allow-Headers'] = '*,x-requested-with,Content-Type,If-Modified-Since,If-None-Match,Auth-User-Token' 
    headers['Access-Control-Max-Age'] = '86400' 
    headers['Access-Control-Allow-Credentials'] = 'true' 

Любая помощь будет оценена. Заранее спасибо.
