Hi,
I can confirm that my python script is working from the command line.
The server (wsgiref) sends a ETag on the initial request with the 200 OK
status code. Additional requests will have the request header
If-None-Match set with the correct ETag value and a 304 Not Modified
response is returned.
The problem appears to be caused by a missing ETag header in the initial
request when running under FastCGI and nginx only. Furthermore, I'm not
sure if the "etag on" configuration option is really doing something.
What do you think?

Hi,
I'm trying to implement conditional requests in Django-hotsauce and
would like to use HTTP_IF_NONE_MATCH to return a 304 Not Modified
response. However in nginx the value of HTTP_IF_NONE_MATCH is
incorrect (a empty string is returned).
Here's my nginx config:
# configuration file /etc/nginx/nginx.conf:

pid /run/nginx.pid;

Questions:
1. Any suggestions why the value of HTTP_IF_NONE_MATCH is not defined
in nginx ?
2. Why is the python script working with wsgiref but not in nginx ?
Thank you in advance,
Etienne
