Looks like the "enctype" is tranlsated into a "content-type" by the browser

Looks like the multipart form data when submitted goes to the server as a content type. One should be able to check this and determine that this is a mutipart request as opposed to a normal request

Headers on a form submitted as a "get"

referer:http://wks3012198:8181/akc/hds-test/fileupload.html

See how the form get and a url submission are identical
