The URL of the server side proxy which will stream the file to the end user.

A proxy will be used when the browser isn't capable of saving files locally. Such browsers are IE version 9 and lower and Safari.

The developer is responsible for implementing the server-side proxy.

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.

The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="<fileName.xslx>".

Example - set the server proxy URL

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
    toolbar: ["excel"],
    excel: {
        proxyURL: "/save"
    },
    dataSource: {
        transport: {
            read: {
                url: "https://demos.telerik.com/service/v2/core/products"
            }
        },
        pageSize: 10
    },
    pageable: true
});
</script>
