It seems like rejected-software forum is flooded with spam, so I decided to ask it here. Is there a way to generate a file -csv for example- on the back-end and serve it to the front-end as a file.

Serve static file [1] function does this for files saved on the disk. I want to be able to generate a file during runtime and serve it to the client. Is this possible?

Thanks,
S

Selim, note the Content-Disposition header in particular.

Thank you Daniel and James! The example works. It's exactly what I was asking for. I got the core idea with the Content Disposition article.
