[Zope] Returning a zip file (downloaded by user)??

[Jan-Wijbrand Kolman]

Hi Aseem,


These headers are set by an app I worked on (although I didn't do 
the zipfile-download-thingy myself). Hope these work for you too...

REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip')
REQUEST.RESPONSE.setHeader('Content-Length', file_size)
REQUEST.RESPONSE.setHeader('Content-Disposition', 'inline; 
filename=%s' % the_name_of_the_file)

Another difference: the download method in aformentioned app does 
not "REQUEST.RESPONSE.write(data)", but just "returns" the data, 
after setting the headers.


regards,
jw
