Hi again! I'm facing a problem using JQuery do access my Elastic Search server using getJSON method on Firefox 3.5 and Google Chrome 4.1.249.104. The problem is that, from Firefox 3.5 on, the XMLHttpRequest must use the JSONP ([https://developer.mozilla.org/en/HTTP\_access\_control](https://developer.mozilla.org/en/HTTP_access_control)) in order to get data from the server, so, even when the server answers ok (Internet Explorer works fine), the firefox browser doesn't allow the content to be loaded, requesting some additional headers or actions (options method before post). Do you know this limitation? As a workaround for the GET methods, I can put an aditional header on the response (Access-Control-Allow-Origin: \*). Is it possible to configure in Elastic Search? Thanks. ---

Actually, I am not too familiar with this Access-Control-Allow-Origin, is this something the server returns in the header for a request? I can add a feature that this can be configured in elasticsearch to be returned. Regarding JSONP, just add callback with your json function to your request, and elasticsearch will return the response in JSONP. I really should document this :). cheers, shay.banon On Sun, Apr 11, 2010 at 9:26 PM, Walendo [jorge.walendowsky@gmail.com](mailto:jorge.walendowsky@gmail.com)wrote: > Hi again! > > I'm facing a problem using JQuery do access my Elastic Search server > using getJSON method on Firefox 3.5 and Google Chrome 4.1.249.104. > > The problem is that, from Firefox 3.5 on, the XMLHttpRequest must use > the JSONP ([https://developer.mozilla.org/en/HTTP\_access\_control](https://developer.mozilla.org/en/HTTP_access_control)) in > order to get data from the server, so, even when the server answers ok > (Internet Explorer works fine), the firefox browser doesn't allow the > content to be loaded, requesting some additional headers or actions > (options method before post). > > Do you know this limitation? > > As a workaround for the GET methods, I can put an aditional header on > the response (Access-Control-Allow-Origin: \*).

Thanks! Actually, this JSONP stuff is new for me (I was developing with flex/java/granite for 3 years). Reading that document I noticed that, passing the header Access-Control-Allow-Origin to tell who might access the page was enough to solve my problem of GETting content from the server. So I hardcoded it in the NettyHttpChannel code to test and it worked. Now I will "unhardcode", use the callback parameter and tell you if it works, ok? Thanks again!

Can you open a feature request so you can provide the list of headers that return as part of each response? I will implement this (should be simple). cheers, shay.banon On Mon, Apr 12, 2010 at 4:26 PM, Walendo [jorge.walendowsky@gmail.com](mailto:jorge.walendowsky@gmail.com)wrote: > Thanks!
