angular 配置http get 缓存

通常做法就是在http request头部的Cache-Control设置为no-cache,Pragma设置为no-cache,

ie的If-Modified-Since设置为’Mon, 26 Jul 1997 05:00:00 GMT’,

写法如下

      }
    };

    $httpProvider.defaults.headers.get={};
  }
  //disable IE ajax request caching
  $httpProvider.defaults.headers.get['If-Modified-Since'] = 'Mon, 26 Jul 1997 05:00:00 GMT';
  // extra
  $httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
  $httpProvider.defaults.headers.get.Pragma = 'no-cache';
