Angularjs removes header on http delete request -

-

i'm trying make http request method delete server , server responds 411, length required. when try set in request seems angular removes it. code have:

var delete = function (url) {   return $http.delete(url,{     method: 'delete',     url: url,     headers: {       'content-length': 0     }   }); };

this see when @ actual request made:

user-agent: mozilla/5.0 (macintosh; intel mac os x 10.9; rv:31.0) gecko/20100101 firefox/31.0 referer:    http://localhost:8877/ host:   localhost:8877 connection: keep-alive accept-language:    en-us,en;q=0.5 accept-encoding:    gzip, deflate accept: application/json, text/plain, */*

no content-length. why remove , how can fix it?

try add body request though empty 1 data: ''
