Ways to control the quantity of ajax POST requests?

Currently, I am utilizing angular (in case it makes a difference) and endeavoring to restrict the quantity of ajax POST requests that my browser sends using javascript - particularly interested in vanilla javascript on the xmlHttpRequest object. Any insights or suggestions would be immensely valued.

Edit 1:

To provide greater clarity, imagine clicking a button which usually triggers 15 simultaneous POST requests - one for each individual "record". My objective is to cap these concurrent requests at 5 maximum. Is there some sort of low-level solution (e.g. javascript xmlHttpRequest) to control the number of these requests? It can also be assumed that the user will consistently use either chrome or safari because this tool is internal.

To achieve this, one can utilize interceptors to capture all requests, verify if they are post methods, and halt the request if a certain limit has been surpassed by leveraging the timeout property in the configurations.

$provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
    var countTimes = 0;
    var stopRequest = $q.defer();
    stopRequest.resolve();
    return {
        'request': function(config) {
            if(config.method == 'POST' && countTimes < someMaxNumber) {
                countTimes += 1;
                return config;
            } else {
                config.timeout = stopRequest.promise;
                return config;
        }
    }
});
$httpProvider.interceptors.push('myHttpInterceptor');
