使nginx缓存无效

使URl无效： --从nginx反向代理缓存中删除页面。 位置^~/invalidate\u cached\u url/{ 允许127.0.0.1； 否认一切； 代理缓存清除nginx\u缓存$arg\u url； }

请使用免费模块。 用法示例：

when i start nginx service it is giving error "unknown directive :proxy_cache_purge". 

• test.com/myimage.png-添加到缓存的url
• test.com/清除/myimage.png-从缓存中删除url

    location / {
        proxy_pass      http://127.0.0.1:8080;

        location ~ /purge(/.*) {    
            proxy_cache_purge cache "$host$1";     
        }   

        location ~* ^.+\.(jpeg|jpg|png|gif|bmp)$ {               
            try_files      $uri @fallback;          
        }           
    }   

    location @fallback {
        rewrite ^(.*)$ /image.php?id=$1;
        proxy_pass      http://127.0.0.1:8080;
    }
