Description
In certain configuration scenarios the "Content-Type" HTTP response header is not of the expected type but rather falls back to the default setting.
I was able to shrink down the configuration to a bare minimum test case which gives some indication that this might happen in conjunction with regex captured in "location", "try_files" and "alias" definitions.
Verfied with Nginx 1.3.6 (with patch.spdy-52.txt applied), but was also reproducible with earlier versions, see
http://mailman.nginx.org/pipermail/nginx/2012-August/034900.html
http://mailman.nginx.org/pipermail/nginx/2012-August/035170.html
(no response was given on those posts)
# nginx -V nginx version: nginx/1.3.6 TLS SNI support enabled configure arguments: --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --sbin-path=/usr/sbin/nginx --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx.pid --user=nginx --group=nginx --with-openssl=openssl-1.0.1c --with-debug --with-http_stub_status_module --with-http_ssl_module --with-ipv6
Minimal test configuration for that specific scenario:
server {
listen 80;
server_name t1.example.com;
root /data/web/t1.example.com/htdoc;
location ~ ^/quux(/.*)?$ {
alias /data/web/t1.example.com/htdoc$1;
try_files '' =404;
}
}
First test request where Content-Type is being correctly set to "image/gif" as expected:
$ curl -s -o /dev/null -D - -H 'Host: t1.example.com' http://127.0.0.1/foo/bar.gif HTTP/1.1 200 OK Server: nginx/1.3.6 Date: Wed, 12 Sep 2012 14:20:09 GMT Content-Type: image/gif Content-Length: 68 Last-Modified: Thu, 02 Aug 2012 05:04:56 GMT Connection: keep-alive ETag: "501a0a78-44" Accept-Ranges: bytes
Second test request where Content-Type is wrong, "application/octet-stream" instead of "image/gif" (actually matches the value of whatever "default_type" is set to):
$ curl -s -o /dev/null -D - -H 'Host: t1.example.com' http://127.0.0.1/quux/foo/bar.gif HTTP/1.1 200 OK Server: nginx/1.3.6 Date: Wed, 12 Sep 2012 14:20:14 GMT Content-Type: application/octet-stream Content-Length: 68 Last-Modified: Thu, 02 Aug 2012 05:04:56 GMT Connection: keep-alive ETag: "501a0a78-44" Accept-Ranges: bytes
