Silent Remote Sending

I really like the plugin!

I use the silent remote feature and want to save an attachment, in order to do this, the form enctype must be set at “multipart/form-data”” Testing the receiver page with an simple html form where the enctype is set correctly, the receiver page works. The same receiver page, when testing the silent remote feature does not work and the only variable between the two is the enctype. Is there a setting or change which can be to set the enctype for silent remote data sending? Note the form is set to use “POST” and the receiver page is ASP with a third party library to manage form data.

Thanks.
