Question

Answer 1

Uploading a file via Ajax is not really possible. You can still upload a file in the background using a hidden iframe and either evaluate the repsonse (which is then inside the iframe) or fire another ajax call after the upload is complete.

    File: 
    Upload

Another option is to use a flash based uploading mechanism (eg. swfupload) instead of the iframe.
