[Zope] Help on downloading data to a file

[Bruce Pearson &/or Gwyn Ingham]

I want to download generated data to a file on the users computer when they
press a button.

The button will call a python script which will generate the data. I'm not
sure how to get the browser to bring up a download dialog and not just
display the data.

I am trying this.

data = 'This is the data that is generated.'

context.REQUEST.RESPONSE.setHeader('Content-Type', 'application/data')
context.REQUEST.RESPONSE.setHeader('Content-Length', len(printed))
context.REQUEST.RESPONSE.setHeader('Content-Disposition',
			   'inline;filename=Data.dat')
return data

This display the data in the browser, but doesn't download it.

Can someone help???

Thanks,

Bruce.
