Hi Guys,
I noticed that Nginx 1.8.X is taking into account the Client Header
“Accept”
for versioning the cache objects, for instance:
This request, generates one object in cache:
curl -sv -o /dev/null 'http://www.foo.bar/image.png -H ‘Accept: /’
And this, generates another one:
curl -sv -o /dev/null 'http://www.foo.bar/image.png -H ‘Accept:
text/html,
image/gif, image/jpeg, *; q=.2, /; q=.2’
This one, another one, and so on:
curl -sv -o /dev/null 'http://www.foo.bar/image.png -H ‘Accept:
text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8’
Considering this behaviour:
it will generate many versions of the same object in cache, using much
more
disc resources, space, IO.
It will reduce the cache hit ratio, as a consequence, will reduce the
performance.
Then, I have a question:
Is there any way to normalize the Accept header, or even ignore it ?
Thanks in advance,
Biazus
