digitalmars.D.learn - Vibe-D File Question

reply Selim Ozel <sozel wpi.edu> writes:
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.
