The URL of the server side proxy which will stream the file to the end user. A proxy will be used when the browser is not capable of saving files locally, for example, Internet Explorer 9 and Safari. The developer is responsible for implementing the server-side proxy. The proxy will return the decoded file with the Content-Disposition header set to attachment; filename="<fileName.pdf>".

The proxy will receive a POST request with the following parameters in the request body:

• contentType - The MIME type of the file.
• base64 - The base-64 encoded file content.
• fileName - The file name as requested by the caller.

Example - setting the server proxy URL

<div id="spreadsheet"></div>
<script>
    $("#spreadsheet").kendoSpreadsheet({
        sheets: [{
            rows: [{
                cells: [{ value: "A" }, { value: "B" }, { value: "C" }]
            }, {
                cells: [{ value: "1" }, { value: "2" }, { value: "3" }]
            }, {
                cells: [{ value: "4" }, { value: "5" }, { value: "6" }]
            }]
        }],
        pdf: {
            proxyURL: "/save"
        }
    });

    var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");
    spreadsheet.saveAsPDF();
</script>
