如何强制stimulsoft在不使用javascript缓存的情况下加载报告

Question

当我更改报告文件的内容并要在浏览器中加载时，即使删除报告文件，然后在浏览器中加载stimulsoft报告，浏览器仍会使用旧的（缓存的）报告文件。

如何在不使用缓存方法的情况下强制stimulsoft加载>

这是我用于加载和显示报告文件的代码。

$('#takereport').on( 'click', function () {
                    StiOptions.WebServer.url = "/js/stimulsoft/handler.php";

                    var options = new Stimulsoft.Viewer.StiViewerOptions();
                    options.appearance.fullScreenMode = false;
                    options.toolbar.showSendEmailButton = true;
                    Stimulsoft.Base.Localization.StiLocalization.setLocalizationFile("/js/stimulsoft/fa.xml",true);
                    var viewer = new Stimulsoft.Viewer.StiViewer(options, "StiViewer", false);
                    viewer.onBeginProcessData = function (event, callback) {
                        <?php StiHelper::createHandler(); ?>
                    };
                    viewer.onBeginExportReport = function (args) {};

                    viewer.onEndExportReport = function (event) {
                        event.preventDefault = true;
                        <?php StiHelper::createHandler(); ?>
                    };
                    viewer.onEmailReport = function (event) {
                        <?php StiHelper::createHandler(); ?>
                    };


                    // Load and show report
                    var date_from=$('#date_from').val();
                    var date_to=$('#date_to').val();
                    var report = new Stimulsoft.Report.StiReport();
                    if($('#report_name option:selected').val()==='xyz')
                    {report.loadFile("/reports/xyz.mrt");
                    }
                    else if($('#report_name option:selected').val()==='pqr')
                    {
                        report.loadFile("/reports/pqr.mrt");
                    }

                    report.dictionary.variables.getByName('date_from').valueObject=date_from;                        report.dictionary.variables.getByName('date_to').valueObject=date_to;


                    viewer.report = report;
                    viewer.renderHtml("content");
                });
