Comment:

 You should now use `StreamingHttpResponse` for such responses.
 `never_cache` won't attempt to compute an Etag for them:
 
https://github.com/django/django/blob/4b27813198ae31892f1159d437e492f7745761a0/django/utils/cache.py#L97

 You can provide an Etag by yourself if you have a meaningful way to
 compute one.

Comment (by Eloff):

 Why is never_cache adding an etag header using an md5 anyway? Presumably
 the purpose of the decorator is to prevent caching, not give the browser
 something it might possibly cache with. If there is a point to adding an
 etag header, make it a large random value, not an md5 hash! Why burn CPU
 just for the hell of it?

Comment (by forest):

 Why not simply not include an ETag header in the response if the content
 is an iterator?  It's not required by the HTTP spec, right?

Comment:

 One possibility is to just use a universally unique id for streamed
 content, since we can't ever predict the unique nature of streamed
 content.

 {{{
 #!python
 import uuid
 response['ETag'] = '"%s"' % uuid.uuid4().get_hex()
 }}}
