Dear list,
I have enabled gzip with
...
gzip on;
gzip_http_version 1.0;
gzip_vary on;
...
to satisfy incoming HTTP 1.0 requests.
In a very similiar setup which got OWASP-evaluated, I read this - marked as a defect:
"The web server sent a Vary header, which indicates that server-driven negotiation was done to determine which content should be delivered. This may indicate that different content is available based on the headers in the HTTP request."
IMHO this is a false positive ...
This is what I send:
HTTP/1.1 200 OK
Server: nginx
Date: Tue, 27 May 2014 17:55:23 GMT
Content-Type: text/html; charset=utf-8
Connection: keep-alive
Vary: Accept-Encoding
X-Content-Type-Options: nosniff
Content-Length: ...
...
What do you think ?
