Hello,

We made changes in our test project, which you specified, and couldn't reproduce the issue. Please send a test project or a modified example of a project from those located on GitHub:

Thank you.

Hello,

We analyzed your project and reproduced the error when using query caching. In this case, the error occurs because the same (cached) response from the server side is returned for the ViewerEvent action, although the URL of the Query String is different. You need to exclude the caching of the ViewerEvent action, or add the following URL to the exceptions: "stiweb_component", "stiweb_action", "stiweb_data"

Thank you.

OK,

How can I exclude idLink param from ViewerEvent?

<script type="text/javascript" src="/Reports/ViewerEvent?idLink=0f07a6dc-e6bd-476b-ba44-0b5b4878ae39&stiweb_component=Viewer&stiweb_action=Resource&stiweb_data=scripts&stiweb_theme=Office2013WhiteBlue&stiweb_loc=TG9jYWxpemF0aW9uL2thLnhtbA%3d%3d&stiweb_cachemode=cache&stiweb_version=2019.1.1">

Hello,

To remove idLink from requests, you can set the following parameter in the Server section:
PassQueryParametersForResources = false

For removing idLink from all viewer requests, you can use the following code on the page after it initialization:

Code: Select all

<script>
    function removeParam(key, sourceURL) {
        var rtn = sourceURL.split("?")[0],
            param,
            params_arr = [],
            queryString = (sourceURL.indexOf("?") !== -1) ? sourceURL.split("?")[1] : "";
        if (queryString !== "") {
            params_arr = queryString.split("&");
            for (var i = params_arr.length - 1; i >= 0; i -= 1) {
                param = params_arr[i].split("=")[0];
                if (param === key) {
                    params_arr.splice(i, 1);
                }
            }
            rtn = rtn + "?" + params_arr.join("&");
        }
        return rtn;
    }

    jsNetCoreViewer.options.requestUrl = removeParam("idLink", jsNetCoreViewer.options.requestUrl);
    jsNetCoreViewer.options.requestAbsoluteUrl = removeParam("idLink", jsNetCoreViewer.options.requestAbsoluteUrl);
    jsNetCoreViewer.options.requestStylesUrl = removeParam("idLink", jsNetCoreViewer.options.requestStylesUrl);

</script>

Thank you.
