Rule Definition
When designing web service to get/put/post data, you want to make sure that you minimize the number of calls between the client application and web service server. By minimizing the number of calls, you improve application speed, reduce communications overhead (why send three request when you can do it by one), and reduce network traffic.

Remediation
Try to create a process queue that will manage all the requests with a limited number of concurrents requests. When a request callback has been managed a new request could be fired.

Violation Code Sample

for (i = 0; i < options.length; i += 1) { 
    $.ajax({
        type: 'GET',
        headers: {'Cookie' : 'USER=' + pseudo },
        url: './launch_analysis?' + choice,
        success: function (data, textStatus, jqXHR) {
        },
        error: function (jqXHR, textStatus, errorThrown) {
            bootbox.alert('error:' + errorThrown);
        }
    });
}
