Assuming that my previous patch adding --method, --body-file and --body-data options is accepted and merged into master, I wanted to propose that we use Content-Type: multipart/form-data and send the whole file as-is when using the --body-file option. This allows us to add the long missing functionality to send files as attachments through wget, without having to change the working of the old options.
The only problem I currently see here is that there remains no way for a user to send body-data in a way that is cannot be seen by another user who can run ps. -- Thanking You, Darshit Shah Research Lead, Code Innovation Kill Code Phobia. B.E.(Hons.) Mechanical Engineering, '14. BITS-Pilani
