Something else is going on. For one thing, I don't see content-type via Apache.
For another, I tried this:
headers['Content-Type'] = contenttype(static_file)
headers['Last-Modified'] = mtime
headers['Pragma'] = 'cache'
headers['Cache-Control'] = 'private'
if request and request.env.http_if_modified_since == mtime:
headers['Content-Type'] = 'text/cached' <<<<<<<<<<<<<<<<<<<<<<<<
raise HTTP(304)
elif request and request.env.http_range:
start_items = regex_start_range.findall(request.env.http_range)
if not start_items:
And I don't see it: I still see text/html.
