Prevent Internet Explorer from caching http calls
Posted By : Kamaldeep Singh | 30-Sep-2015
In this blog, I will let you know how to prevent Internet Explorer browser to cache ajax http calls.
Recently I met with a problem in which I was not able to get the updated data from server in IE. This case was generated on second time call. Having the same parameters, the server gives response to the first $http call but denies further $http calls on same URL with same parameter. As IE used to cache the values of first call made. Yes there could be case where you actually get the same response via requesting the same request parameter but if your API is returning different values on same API with the same parameter then this is gonna be prevented in Internet Explorer. So to prevent this, add the following lines of code in your angular configuration block as :
var mainApp = angular.module('mainApp', ['config']);
mainApp.config(['$httpProvider'function( $httpProvider) {
if (!$httpProvider.defaults.headers.get) {
$httpProvider.defaults.headers.get = {};
}
$httpProvider.defaults.headers.get['If-Modified-Since'] = 'Mon, 26 Jul 1997 05:00:00 GMT';
$httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
$httpProvider.defaults.headers.get['Pragma'] = 'no-cache';
}]);
Hope this thing helps you.
