Serving dynamically generated contents as static download

[Anton Shvein]

Hi,

Is there any way to push dynamically generated binary content as if it where regularly downloaded  binary file?

Hi Toha,

  If I understand you correctly you are looking for http://nitrogenproject.com/demos/contenttype

  If that doesn't help let me know.

Hi Anton!

If I'm understanding your needs (wanting to dynamically generate
streamed binary content), there isn't a great way to deal with this.
There are two ways to deal with this:

1) Using the underlying server's streaming mechanisms (such as making
a cowboy-specific dispatch table to targets a cowboy handler module to
deal with the streaming), or a yaws outfile.

2) Using cowboy, there's a bit of a hack that can work in
simple_bridge if you're using cowboy. If your module's main() function
returns the tuple: {stream, StreamFun} where StreamFun is a function
with arity 2 that (fun(Socket, Transport) - Transport being a ranch
transport). Really, this is just a shortcut way that allows you to
use Transport:send(socket) to send data. I'll admit I haven't done
this before, but it should work with a little bit of tinkering.

Adding this as an actual option to simple_bridge and Nitrogen would
probably be worthwhile.

If, however, you are just generating a small-ish amount of data, then
doing as Stuart recommends would be much easier.
