I use Live HTTP headers to check what goes through : http://localhost:8080/charts/data/dataId/KBU GET /charts/data/dataId/KBU HTTP/1.1 Host: localhost:8080 User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.11) Gecko/2009060308 Ubuntu/9.04 (jaunty) Firefox/3.0.11 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en,de;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: JSESSIONID=1gxaom5muzh66 HTTP/1.x 200 OK Content-Type: text/csv; charset=UTF-8 Content-Length: 5726 Server: Jetty(6.1.16) thanks again zedros On Tue, Jul 28, 2009 at 8:59 AM, Juri Prokofiev<proj...@gmail.com> wrote: > To set headers to a resource you need to extend setHeaders method from > WebResource.
