How to handel session in Ajax and Servlet

I am developing a website using Java/Servlet and Ajax, with some libraries of D3.js The problem when I access the website from different PC or phones, I submitted the data successfully using the HTML form and it gives me the results as I want, BUT the problem when I use the form to submit new data using the same machine (Iphone or PC), the showing results still for the old query, when I check the server I see the new files created for the new query but in my phone or PC the results still showing the old query data.

Any help or ideas.

// form submit and validation
$("input,textarea").jqBootstrapValidation({
        preventSubmit: true,
        submitError: function($form, event, errors) {
            // additional error messages or events
        },
        submitSuccess: function($form, event) {
            event.preventDefault(); // prevent default submit behaviour
            // get values from FORM
            var vendor = $("input#vendor").val();
            var product = $("input#product").val();
            var version = $("input#version").val();

        var checkbox_value = "";
            $(":checkbox").each(function () {
                var ischecked = $(this).is(":checked");
                if (ischecked) {
                    checkbox_value += $(this).val();
                }
             });

        $.ajax({
                url: "servletname",
                type: "GET",
                data: {
                    vendor: vendor,
                    product: product,
                    version: version,
                    dependency: checkbox_value
                },
                cache: false,
                success: function(responseText) {
                      .... 
                }
