I try to show SVG file in HTML or separate tab but Nginx offers me to download it.
I took normal SVG file which works on another site but not in my server.
Where is a problem?
Here is an example http://proximax.ru/media/content/final/plane2.svg
Also here SVG in HTML http://proximax.ru/index/
The of your image is noted as application/octet-stream
which a browser can only offer to download as it does not know how to interpret it.
From your index.html
file it is clear that you were playing around with variations of the MIME-type, and it is unclear whether the standard requires image/svg or image/svg+xml (or standards being what they are, something else entirely).
I fixed it.
I added to /etc/nginx/mime.types
image/svg+xml svg svgz;
Then I checked that server responses correctly
wget -O - -S http://proximax.ru/media/content/final/avW30U.svg > /dev/null
..
Content-Type: image/svg+xml
..
Also I turned off other virtual spaces for be clear.
In my case, I put default_type application/octet-stream;
after the include mime.types;
cause the problem. And simply switch them fixed it. ^_^
