Description
Looks as debug_output mistakenly writes file check string in it's output while actually making right things.
nginx.conf:
user www-data; worker_processes auto; pid /run/nginx.pid; include /etc/nginx/modules-enabled/*.conf; events { worker_connections 768; debug_connection 127.0.0.1/32; } http { # skipped default settings from package's nginx.conf server { listen 80; location / { return 403; } location /test { root /var/www/html; try_files $uri =404; proxy_pass http://127.0.0.1:8080; } } server { listen 8080; location /test { return 302 /test1; } } }
Create file /var/www/html/test/test.html (empty, using touch).
Then execute curl -v "_ttp://127.0.0.1/test/test.html"
, it returns 302 as expected.
Now execute curl -v "_ttp://127.0.0.1/test/test.html_"
, it returns 404 as expected too. And what debug log says:
2022/10/11 14:02:12 [debug] 12395#12395: *132 try files handler 2022/10/11 14:02:12 [debug] 12395#12395: *132 http script var: "/test/test.html_" 2022/10/11 14:02:12 [debug] 12395#12395: *132 trying to use file: "/test/test.html_" "/var/www/html/test/test.html_" 2022/10/11 14:02:12 [debug] 12395#12395: *132 trying to use file: "=404" "/var/www/html=404" 2022/10/11 14:02:12 [debug] 12395#12395: *132 http finalize request: 404, "/test/test.html_?" a:1, c:1 2022/10/11 14:02:12 [debug] 12395#12395: *132 http special response: 404, "/test/test.html_?" 2022/10/11 14:02:12 [debug] 12395#12395: *132 http set discard body 2022/10/11 14:02:12 [debug] 12395#12395: *132 HTTP/1.1 404 Not Found
Ok, let's create file /var/www/html=404 (empty, using touch). And execute curl -v "_ttp://127.0.0.1/test/test.html_"
again. We get 404 again as expected but debug log still shows that nginx checks file existence:
2022/10/11 14:07:36 [debug] 12395#12395: *135 try files handler 2022/10/11 14:07:36 [debug] 12395#12395: *135 http script var: "/test/test.html_" 2022/10/11 14:07:36 [debug] 12395#12395: *135 trying to use file: "/test/test.html_" "/var/www/html/test/test.html_" 2022/10/11 14:07:36 [debug] 12395#12395: *135 trying to use file: "=404" "/var/www/html=404" 2022/10/11 14:07:36 [debug] 12395#12395: *135 http finalize request: 404, "/test/test.html_?" a:1, c:1 2022/10/11 14:07:36 [debug] 12395#12395: *135 http special response: 404, "/test/test.html_?" 2022/10/11 14:07:36 [debug] 12395#12395: *135 http set discard body 2022/10/11 14:07:36 [debug] 12395#12395: *135 HTTP/1.1 404 Not Found
