Welcome to tutorial no. 1 in our Resumable file uploader series. How many times have you tried to upload a large file only to know that it failed because of a network issue! When you re-upload the file again, the upload starts from the beginning :(. Not cool at all. This is where resumable file uploaders come in handy. Resumable file uploaders allow the file upload to start right from the point where it stopped instead of uploading the whole file again.
