Hi, I’m using nginx 1.8.0 on Ubuntu 14.04 LTS. # nginx -V nginx version: nginx/1.8.0 built with OpenSSL 1.0.1f 6 Jan 2014 TLS SNI support enabled configure arguments: --with-cc-opt=‘-g -O2 -fPIE -fstack-protector –param=ssp-buffer-size=4 -Wformat -Werror=format-security -D\_FORTIFY\_SOURCE=2 -mtune=corei7-avx -march=corei7’ –with-ld-opt=‘-Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now -mtune=corei7-avx -march=corei7’ --prefix=/usr/share/nginx –conf-path=/etc/nginx/nginx.conf –http-log-path=/var/log/nginx/access.log –error-log-path=/var/log/nginx/error.log –lock-path=/var/lock/nginx.lock –pid-path=/run/nginx.pid –http-client-body-temp-path=/var/lib/nginx/body –http-fastcgi-temp-path=/var/lib/nginx/fastcgi –http-proxy-temp-path=/var/lib/nginx/proxy –http-scgi-temp-path=/var/lib/nginx/scgi –http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit –with-file-aio --with-http\_ssl\_module --with-http\_stub\_status\_module –with-http\_realip\_module --with-http\_auth\_request\_module –with-http\_addition\_module --with-http\_geoip\_module –with-http\_gunzip\_module --with-http\_gzip\_static\_module –with-http\_image\_filter\_module --with-http\_perl\_module –with-http\_secure\_link\_module –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/headers-more-nginx-module –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-auth-pam –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-cache-purge –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-development-kit –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-echo –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/ngx-fancyindex –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-lua –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/nginx-upstream-fair –add-module=/opt/rebuildnginx/nginx-1.8.0/debian/modules/set-misc-nginx-module I have noticed that when I restart nginx (using restart or just simple stop and then start) the cache is not invalidated as it used to be. After each restart I get HIT for all pages that were valid in cache before the restart. Did anyone else noticed this behavior ? If yes, how did you fix it?

If yes, how did you fix it? Caches are not expected to be invalidated on restart (and they never used to be). If you want nginx to avoid using previously cached responses after a restart, you can remove the cache directory. – Maxim D. > **[nginx](http://nginx.org/)**
