68 当开启缓冲时,nginx尽可能快地从被代理的服务器接收响应,再将它存入<link id="proxy_buffer_size"/>和<link id="proxy_buffers"/>指令设置的缓冲区中。如果响应无法整个纳入内存,那么其中一部分将存入磁盘上的<link id="proxy_temp_path">临时文件</link>。<link id="proxy_max_temp_file_size"/>和<link id="proxy_temp_file_write_size"/>指令可以控制临时文件的写入。 |

966 保存文件的修改时间根据接收到的<header>Last-Modified</header>响应头来设置。响应都是先写到临时文件,然后进行重命名来生成的。从0.8.9版本开始,临时文件和持久化存储可以放在不同的文件系统,但是需要注意这时文件执行的是在两个文件系统间拷贝操作,而不是廉价的重命名操作。因此建议保存文件的路径和<link id="proxy_temp_path"/>指令设置的临时文件的路径在同一个文件系统中。 |
