[xwiki-users] Caching resources

Hello, i would like to active cachin on /xwiki/bin/skin/resources/* as, obviously, skin doesn't change often :) As you can see, by default, xwiki forbid caching... What do i need to change for this caching? Thank you. ----------- GET /xwiki/bin/skin/resources/js/scriptaculous/effects.js HTTP/1.1 Host: ********* User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.12) Gecko/20100101 Firefox/10.0.12 Accept: */* Accept-Language: fr-be,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Connection: keep-alive Referer: ********** Cookie: JSESSIONID=*********.undefined; language=en; gh.i=%7B%7D; AJS.conglomerate.cookie=||||||||||||||||||||||||||||||upm.tab=install If-Modified-Since: Tue, 26 Jun 2012 10:06:58 GMT Authorization: Basic ZGVsYmQ6c2VpcmprMjA0NA== HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Pragma: No-cache Cache-Control: public Expires: Sat, 02 Mar 2013 17:22:25 GMT Last-Modified: Tue, 26 Jun 2012 10:06:58 GMT Content-Type: text/javascript;charset=UTF-8 Content-Language: en Content-Length: 25003 Date: Thu, 31 Jan 2013 17:22:25 GMT String.prototype.parseColor=function(){var a="#"; if(this.slice(0,4)=="rgb("){var c=this.slice(4,this.length-1).split(","); ----------- David Delbecq
