Uploading files different servers at once using a single html Form

Is there a way to make a form where it can simultaneously upload to several servers at once?

Currently in my web application, I am asking the users to type in some info + select a few files to upload.

• Title, Description, Info, etc
• File 0
• File 1
• File 2
• File ...

On the backend, I'm using Pylons. Currently it accepts POST of (info + all files), processes the info and the first file (file 0), and uploads them again to Amazon S3. I only need to process info and the 'file 0' on my own server, the rest of the files I can pass through directly to S3 via a POST.

Is there a way to make a form开发者_JS百科 where the info+file0 will be POST'ed to one server, and the rest of the files be POST'ed directly to S3?

While you could employ JavaScript trickery to make clicking on a submit button result in multiple POST requests to multiple servers, such a solution will almost certainly cause more problems than it solves. You should probably stick with your current method.

My solution would involve ajax upload(s) to S3 as a first step. Once you're done with the files, you can submit all the other fields (not ajax) to your webserver, eventually adding the generated S3 links.
