Question

I’m using uploadify with MVC 3. When loading the page I have extra request to the page action – so many as uploadify units on the page.
How to tell uploadify not to do that?:)

Answer 1

I saw the same thing in a Ruby Sinatra app I built. Dug into it a bit and realized that swfUpload was looking for a button image at the wrong url. I got it to work correctly by initializing the swfUpload button_image_url property to the Uploadify settings.buttonImage property:

var swfUploadSettings = {
    assume_success_timeout   : settings.successTimeout,
    button_placeholder_id    : settings.id,
    button_width             : settings.width,
    button_height            : settings.height,
    button_image_url  : settings.buttonImage,
    button_text              : null,
    ....
