如何避免与fastcgi_cache的url？
不需要caching列表，例如
projectdomain.com/a projectdomain.com/b projectdomain.com/c/d vi /etc/nginx/nginx.conf
http { fastcgi_cache_path /var/cache/fastcgi/projectdomain.com levels=1:2 keys_zone=projectdomain.com:10m inactive=5m; add_header X-Fastcgi-Cache $upstream_cache_status; ...
vi /etc/nginx/conf.d/default.conf
map $request_uri $dont_cache_uri { default 0; projectdomain.com/a 1; projectdomain.com/b 1; projectdomain.com/c/d 1; } server { listen 80; server_name projectdomain.com www.projectdomain.com; access_log /var/log/nginx/projectdomain.com.access.log; root /var/www/html/projectdomain.com; index index.php index.html index.htm; try_files $uri $uri/ /index.php?$query_string; client_max_body_size 1G; location ~ ^/sitemap/(.*)$ { root /var/www/html/projectdomain.com/app/Sitemap/SitemapGz; } location /robots.txt { alias /var/www/html/projectdomain.com/app/robots.txt; } location ~ ^/(android-chrome-36x36.png|android-chrome-48x48.png|android-chrome-72x72.png|android-chrome-96x96.png|android-chrome-144x144.png|android-chrome-192x192.png|apple-touch-icon-57x57.png|apple-touch-icon-60x60.png|apple-touch-icon-72x72.png|apple-touch-icon-76x76.png|apple-touch-icon-114x114.png|apple-touch-icon-120x120.png|apple-touch-icon-144x144.png|apple-touch-icon-152x152.png|apple-touch-icon-180x180.png|apple-touch-icon-precomposed.png|apple-touch-icon.png|browserconfig.xml|favicon-16x16.png|favicon-32x32.png|favicon-96x96.png|favicon.ico|manifest.json|mstile-70x70.png|mstile-144x144.png|mstile-150x150.png|mstile-310x150.png|mstile-310x310.png|safari-pinned-tab.svg) { root /var/www/html/projectdomain.com/app/favicons; } location ~ ^/(images/|javascripts/|stylesheets/|fonts) { root /var/www/html/projectdomain.com/app/assets; access_log off; expires max; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi_params; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 32k; fastcgi_buffers 8 32k; # cache fastcgi_cache projectdomain.com; fastcgi_cache_valid 200 60m; fastcgi_cache_methods GET HEAD; fastcgi_cache_key $scheme$request_method$host$request_uri; fastcgi_ignore_headers Cache-Control Expires Set-Cookie; fastcgi_cache_bypass $dont_cache_uri; fastcgi_no_cache $dont_cache_uri; } }
为避免caching请求，应该一起使用fastcgi_no_cache和fastcgi_cache_bypass 。 第一个告诉nginx不caching响应，第二个告诉nginx不要在caching中find文档。
例如，要避免使用查询stringcaching任何请求：
fastcgi_cache_bypass $is_args; fastcgi_no_cache $is_args;
为避免使用名为“logged_in_user”的cookiecaching请求，请执行以下操作：
fastcgi_cache_bypass $cookie_logged_in_user; fastcgi_no_cache $cookie_logged_in_user;
但是，为了避免caching特定path，您需要将其与map结合起来，该map列出了您不想caching的url。 请注意， map必须出现在每个server块之外，并在http块内。
map $request_uri $dont_cache_uri { default 0; /a 1; /b 1; /c/d 1; }
那么你可以避免caching所有上述。
fastcgi_cache_bypass $is_args $cookie_logged_in_user $dont_cache_uri; fastcgi_no_cache $is_args $cookie_logged_in_user $dont_cache_uri;
