Hi,

I’m using Rails Metal to serve certain files,  
But i don’t know how to change the filename …

Here is the code in Metal where i send the file :  
[200, { ‘Content-Type’ =\> file.content\_type}, [file.read]]

I tried to specify ‘filename’=\>‘test.zip’… but without success…

Anyone has a clue ?

Thanks,  
regards.

Are you trying to set the name that the browser saves the file as? If  
so then you need to set a Content-Disposition header ( see
