I'm running into the following error message when using elasticsearch-js[https://github.com/elasticsearch/elasticsearch-js/](https://github.com/elasticsearch/elasticsearch-js/)client: > No 'Access-Control-Allow-Origin' header is present on the requested > resource. Origin '[http://localhost:9090](http://localhost:9090)' is therefore not allowed access.

Yup this didn't have anything to do with the client. For anyone else who is a big fan of pairing elastisearch with APIGEE ... the solution is here: [api - Apigee Pre-Flight Options Requests - Stack Overflow](http://stackoverflow.com/questions/21193647/apigee-pre-flight-options-requests) On Saturday, March 29, 2014 9:30:36 AM UTC-5, pulkitsinghal wrote: > I'm running into the following error message when using elasticsearch-js[https://github.com/elasticsearch/elasticsearch-js/](https://github.com/elasticsearch/elasticsearch-js/)client: > > > No 'Access-Control-Allow-Origin' header is present on the requested > > resource.
