Hi, I bet you have enabled HTTP compression in `elasticsearch.yml`. Can you disable it and see if it works? Daniel ---

Hi, Daniel. Yes, the http compression was enabled, after disable it, CORS works perfectly. Is this a bug or a expected behavior? Thank you. ---

Hi, I've expected that. I ran into the same problem when testing HTTP compression for 5.0. In 5.0 this problem will be gone anyway but I think we should fix this for Elasticsearch 2.x too (so I think this is a bug). Can you please create a bug ticket on Github and paste the link here? Daniel ---

Hi, thanks, I've commented on the ticket. As this is a fairly local change I assume this will get fixed with the next release. If I have some cycles to spare I can fix it soon. Daniel ---

Hi, I created [https://github.com/elastic/elasticsearch/pull/18101](https://github.com/elastic/elasticsearch/pull/18101) which I expect to be in soon and the issue will be fixed with Elasticsearch 2.3.3. Daniel ---
