ip_hash里边的
n = p / (8 * sizeof(uintptr_t));
m = (uintptr_t) 1 << p % (8 * sizeof(uintptr_t));
的作用是什么啊？

还有想问下：通过ip_hash进行负载均衡后，上游的服务器对请求处理的返回结果，能在原先的ip_hash里边的到吗？

以下代码产生alter: the process is exited!怎么修改好啊？
  u_char *qs_start = (u_char *)r->args_start;
   //如果是 u_char *qs_start = "n=n01&m=a"; 就不会产生alter: the process is exited!
    u_char *getpar;
    ngx_str_t nodeid = ngx_string("");
    ngx_str_t hostid = ngx_string("");
    nodeid.data = ngx_pcalloc(r->pool,sizeof("n01"));
    hostid.data = ngx_pcalloc(r->pool,sizeof("a"));
    nodeid.len = 4;
    hostid.len = 2;
    getpar = (strstr(qs_start, "n="));
    getpar += 2;

张哥，没整明白，有没有 说明书啊？350015800

为什么我打开ASP的站显示的是文件列表！！！打开源码文件，显示的是源代码

访问http://127.0.0.1/phpmyadmin/  页面出错是怎么回事

接下
rewrite ^/category-([0-9]+)-b([0-9]+)-min([0-9]+)-max([0-9]+)-attr([^-]*)-([0-9]+)-(.+)-([a-zA-Z]+)(.*).html$  /category.php?id=$1&brand=$2&price_min=$3&price_max=$4&filter_attr=$5&page=$6&sort=$7&order=$8 last;

下面还有发不上去了，过滤了特殊字符

接下

问个问题，域名从新网转入godaddy时，域名解析设置怎么办？ 会不会出现网站几天不能解析？

这几天网站上午访问好像有点问题，打不开：）

请教一个问题：我想做一个比较大型的网站，从前端到后端，希望大哥给个方案，一直都是做小型的网站，现在有一个大型的网站部署，希望多帮忙，包括服务器配置，网络架构这方面给点建议，帮助下我。谢谢了
