I'm seeing that while uploading the file, RadAsyncUpload is also sending set of additional information as part of the payload (form-data fields) like "rauPostData", "fileName", "contentType", and others data pieces (see attachment).
I'm thinking whether it is possible to add additional custom fields to the payload mainly the CSRF token which will help me evaluate the authenticity of the file upload before it gets processed on the server.
I'm doing all CSRF validation through HttpModule and hence I cannot use Custom RadAsyncUpload Handler which for me is not a viable solution as the module will not let the request reach till this point.
Is there any degree of customization which can help me through this? Any help will be truly appreciated.
Thanks,
