This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I've successfully implemented a single file download using the Stream result. How do I deal with the situation where I have multiple files to download? I want to allow the user to select a number of files and then download all the chosen files, rather than force the user to select a file, download it, select another file, download it etc etc.
HTTP is a single request- single response protocol. Your options are to either force your user to click multiple times, or make some server-side functionality to put multiple files in an archive file and return that as the response.
