I think what I would do in your case the following:

* Capture the filestream and post it to the server
* On the server capture the stream and write it out somewhere in a temp location with a non-accessible name or in a DB
* Have another request that allows you to download that same binary content to a local file
* That request should return a URL where the file/content can be picked up (a URL) (in ASP.NET it'll be like Response.DownloadFile() or MVC FileResult)
* On the client capture the URL then use `location.href=url` to navigate there which should give you to the dl dialog

This gives you a download dialog and also a file name (determined by the server), but you can't control the location of the save operation.

You can create a file service server class that can simplify this stuff by managing the ID generation, storage and cleanup for you.
