You can use the CherryPy server with Pylons, which I assume is what
Sandeep is doing. But I don't understand why he's using the CherryPy
header API, and I'd be surprised if it even works in a Pylons
controller.
Here's how I force a text file to be downloaded rather than displayed
in Pylons 1:
response.content_type = "text/plain"
response.charset = "utf-8"
response.headers["Content-disposition"] = (
"attachment; filename=MyChemicals.txt")
In Pyramid you'd set the corresponding ``self.request.response_*``
attributes (only a few of these are defined, they may not cover all
these headers). Or create a Response object, set them on it, set the
body to the file content, and return the response.
