[Grok-dev] Get files

[zavi]

Thank you everyone for the very quick and detailed responses.

Some follow-up questions - 
1. If I want to use the zope.file.download, I see here
http://svn.zope.org/zope.file/branches/ajung-blobs/src/zope/file/download.py?rev=72831&view=markup
That it is related to a browser view. Which means I have to access my grok
application using a browser, which pops up a dialog for downloading the file
etc.
Is there a way to bypass that, by having the client send a REST request with
the file name and get it directly? 
I need to have grok display pages, but not always for the particaulr task of
sending files to the client.

2. Can I improve performance using sendfile()? is this integrated (or can be
integrated) to Grok in some way?
For example I managed to write a simple (non-grok) application that uses
mod_wsgi directly to work with x-sendfile. Maybe this is possible somehow
with grok?
I see there's a sendfile patch for zope2
http://gabbpuy.blogspot.com/2007/03/sendfile-patch-for-zope2.html
Can this perhaps be integrated to grok?

Thank you
