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

[Aseem Mohanty]

Hi,
I have a zip file that I create on the fly which is to be returned to 
the user. The process goes like this:

1. User clicks on a link.
2. External method creates a zip file and puts it in a temp folder( file 
system folder not Zope temp)
3. External method (same one) returns the zip file as part of response 
as type application/x-zip

The following is what I do in to get it done:(part 3 i.e.)

        zip_size = stat(zip_file_name).st_size
        zip_file = open(zip_file_name)
        zip_data = zip_file.read()
        zip_file.close()
       
        REQUEST.RESPONSE.setStatus('OK')
        REQUEST.RESPONSE.setHeader('Content-Type','application/x-zip')
        REQUEST.RESPONSE.setHeader('Content-Length',zip_size)
        REQUEST.RESPONSE.write(zip_data)

but when I try it out the following happens:
- the zip file is created
- zip_data has the data (of course)
- i am prompted to download something of type application/x-unknown-content
- if i save the file it has zero length

so what am I doing wrong or not doing here, that needs to be done to get 
this right??
TIA
AM
