应用场景，win下面根据不同的网址代理到不同的php.exe

## 虚拟配置文件 ##

# vhost/baidu.com.conf
    server {
        listen 80;
        listen 443 ssl;
        server_name local.baidu.com www.baidu.com test.baidu.com;
        root d:/website/baidu.com/src/public;
        #root d:/website/baidu.com/src;
        index index.html index.htm index.php;
    
        ssl on;
        ssl_certificate     d:/website/ssl/www.crt; 
        ssl_certificate_key d:/website/ssl/www.com.key; 
    
        ssl_session_cache    shared:SSL:10m;
        ssl_session_timeout  10m;
        ssl_protocols  SSLv2 SSLv3 TLSv1;
        ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
        ssl_prefer_server_ciphers   on;
    
    
        set $pass_to php_pool_pc ;
        set $log_upstream 0;
    
        if (!-e $request_filename) {
            rewrite  ^/(.*)$  /index.php?_route_=$1  last;
            break;
        }
    
        if ( $request_uri ~ ^$ ) {
            set $pass_to php_pool ;
        }
    
        if ( $query_string ~ route=journal2 ) {
            set $pass_to php_pool_pc2 ;
        }
    
        if ( $query_string ~ route=catalog) {
            set $pass_to php_pool_pc3 ;
        }
    
        if ( $query_string ~ "route=catalog/product" ) {
            set $pass_to php_pool_pc_admin ;
        }
    
        if ( $request_uri ~ ^/admin ) {
            set $pass_to php_pool_pc_admin ;
        }
    
        location ~ \.php$ {
            set $log_upstream 1;
            add_header X-PASS-TO "$pass_to" ;
            fastcgi_pass   $pass_to;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }   
    
    
        access_log logs/pc-upstream.log upstream_log if=$log_upstream;
        access_log logs/pc.log main;
    }

这算是一个特别蛋疼的解决方案，因为 win下面没有php-fpm，自动按需进行启动新进程。如果php特别稀烂的时候，就无法形容了。

*  新增了 add\_header X-PASS-TO 为了方便调试
 *  注意 `set $pass_to php_pool_pc`; 必须在 rewrite 之前，否则会报错 `$pass_to` 为空 500。
