Thank you.
Absolutely! Achieving this is possible by utilizing Ajax along with the FormData API:
var uploadedFile = document.getElementById('fileInput').files[0],
formData = new FormData();
formData.append('file', uploadedFile);
Ext.Ajax.request({
url: '/upload/files',
rawData: formData,
headers: {'Content-Type':null}, //using FormData content type
success: function(response){
}
});

I haven't personally verified this, but I believe it should be beneficial.
