负载均衡(nginx 1.11.2)：
文件结构如下，content文件为网站静态资源文件夹，nginx.conf为配置文件。
nginx.conf内容如下：
#user nobody;
# multiple workers works !
worker_processes 8;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
#pcre_jit on;
events {
worker_connections 8192;
}
http {
## 其他配置
include mime.types;
default_type application/octet-stream;
client_max_body_size 100M; ## 页面如果要上传大文件，要加上该属性。
sendfile off;
server_names_hash_bucket_size 128;
map_hash_bucket_size 64;
client_body_timeout 10;
client_header_timeout 10;
keepalive_timeout 30;
send_timeout 10;
keepalive_requests 10;
## 添加两个负载均衡服务，每个管理两个站点（权重weight用来设置负载比例）

共享session：
另外，需要确认该机器的注册表值正确，端口号值要一致（注册表中为16进制）。
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParameters]
结束后重启ASP.NET 状态服务，设为自启。
共享文件：
- 在每个站点服务器建立同名，同密码的帐号。并选择账户所有者。
在运行中输入lusrmgr.msc打开本地用户和组管理界面
创建账户，密码选择“永不过期”
用户属性中，添加隶属账户“administrators”
在每个站点所属的程序池添加标识用户。
在作为文件服务器的机器，创建网络共享文件夹。
创建文件夹，并添加everyone及IUSER_SHARE权限
文件夹属性中添加网络共享。
为IIS的默认站点添加虚拟目录，路径选择共享文件夹
启用iis中的目录浏览
部分文件无法读取的情况下，添加crossdomain.xml文件，至虚拟目录所在站点的根目录下（Default Web Site）
内容如下（星号*代表允许所有域名的访问）：
<?xml version="1.0" encoding="utf-8"?> <cross-domain-policy> <allow-access-from domain="*"/> </cross-domain-policy>
