反向代理用来隐藏服务器细节,作为负载均衡就能组建分布式集群,提供容灾、高可伸缩性等;
正向代理用来隐藏客户端细节,比如翻墙、跳转机访问、隐藏IP地址等。

第1种。参考官方文档:
“When buffering is enabled, nginx receives a response from the proxied server as soon as possible, saving it into the buffers set by the proxy_buffer_size and proxy_buffers directives. If the whole response does not fit into memory, a part of it can be saved to a temporary file on the disk. Writing to temporary files is controlled by the proxy_max_temp_file_size and proxy_temp_file_write_size directives.
When buffering is disabled, the response is passed to a client synchronously, immediately as it is received. nginx will not try to read the whole response from the proxied server. The maximum size of the data that nginx can receive from the server at a time is set by the proxy_buffer_size directive.”
