Disabling caching for Angular AJAX requests in Internet Explorer - a step-by-step guide

My Angular application successfully makes HTTP GET requests to the server when accessed on Chrome and Firefox. However, I recently encountered an issue with Internet Explorer where it caches the GET response. This causes a problem when I need to retrieve updated information after making a POST request. Specifically, in IE, the cached GET response is retrieved instead of the new data. I am looking for a way to disable caching specifically for IE without impacting other browsers.

'If-None-Match': '*'

I attempted to use the above code snippet as a request header for my GET calls, but found that it disabled caching universally rather than just for IE. Can anyone suggest a solution to conditionally disable caching for IE only? Alternatively, are there alternative methods to achieve this desired outcome?

CSS

<link rel="stylesheet" type="text/css" href="styles.css">

Python

if 'cache' in response.headers:
    del response.headers['cache']
response.headers['pragma'] = 'no-cache'
response.headers['expires'] = 'Sat, 01 Dec 2001 00:00:00 GMT'

After analyzing the information provided, I successfully implemented this solution for a specific request within a controller without altering the global defaults:

var customConfig = {
    headers: {
        common: {
            "Cache-Control": "no-cache",
            "If-Modified-Since": "0",
            "Pragma": "no-cache"
        }
    }
};

$http.get("path/to/file.json", customConfig)
    .then(function (response){
        //perform actions
    });

When using $http in Internet Explorer, you may encounter issues where the response code is not 200 or 304, causing it to rely on local cache instead.

To address this problem, consider adding headers to the $httpProvider as shown below:

angular.module(ApplicationConfiguration.applicationModuleName)
.config(['$httpProvider', function($httpProvider) {
    //initialize get if not there
    if (!$httpProvider.defaults.headers.get) {
        $httpProvider.defaults.headers.get = {};    
    }    

    //disable IE ajax request caching
    $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';
}]);

Although this thread is old, I recently conducted a test and found that none of the discussed headers are recognized by IE11.

Since IE only considers the URL to determine caching, I decided to add a date to the query string like so:

$http.get("https://myURLWithoutParameters"?t=" + new Date().getTime())
.then(function (response) {
  // Manage response
}, function (response) {
  // Error handling
});
