Nginx Gzip file download not working

Server NGINX
1

Hi All,

When i try to download a file using “curl -H “Accept-Encoding: gzip”
http://abc.com/xx.epub” ,almost 99% file downloads and then it hangs and
end up with this message “curl: (18) transfer closed with 2693 bytes
remaining to read”. Please help.Do i need to change anything in server
side to make this work?

this is my gzip configuration in nginx.conf

gzip  on;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_proxied any;
gzip_min_length  1100;
gzip_buffers 16 8k;
gzip_disable "MSIE [1-6].(?!.*SV1)";
gzip_vary on;

Please help me…

Can you set up a test system, and find a minimum configuration that
shows the problem you are seeing?

The reason I ask, is: with this gzip-related configuration, and the rest
being defaults, I don’t think that the gzip handler is involved here.

When I try the following test:

nginx.conf:

events {
worker_connections 1024;
debug_connection 127.0.0.1;
}

http {
include mime.types;

gzip on;
gzip_min_length 1100;

server {
    listen       8000;
}

}

create my test file

perl -e ‘print “1234567890” x 111’ > html/xx.epub

Then I can run the curl commands to get the file:

curl -I http://localhost:8000/xx.epub
curl -I -H ‘Accept-Encoding: gzip’ http://localhost:8000/xx.epub

and they show the same response.

If I add the line

gzip_types text/plain;

to nginx.conf and reload, then the plain curl shows me

Content-Type: text/plain
Content-Length: 1110

while the gzip one shows

Content-Type: text/plain
Content-Encoding: gzip

So: I’m unable to replicate the problem you report; and it doesn’t
immediately seem related to gzip.

Can you provide a replication recipe that someone else could run to see
the same problem?

Do you see the problem with any other file? Or with the same file on a
different server?

Also, the output of “nginx -V” and the logs, are likely to be useful.

Good luck with it,
