That's not my server response headers, so it's being served for a long time and others server are accepting it without any issues... So why node.js is not willing to accept that one when i'm trying to proxy request further by setting it via .setHeader() ?\r\n\r\n","author":{"url":"https://github.com/Somebi","@type":"Person","name":"Somebi"},"datePublished":"2018-06-24T18:25:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/21509/node/issues/21509"}
