SSI：Server Side Include，是一种基于服务端的网页制作技术，
Nginx ssi 的例子如下：
It took a little while to figure this out and it’s handy for creating one-off sites with “dynamic” content without a web framework.
user nginx;
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
keepalive_timeout 10;
gzip on;
server {
server_name localhost;
charset utf-8;
access_log /var/log/nginx/access.log;
root /var/www;
location = / {
rewrite ^ /home redirect;
}
location / {
ssi on;
set $inc $request_uri;
if (!-f $request_filename) {
rewrite ^ /index.html last;
}
if (!-f $document_root$inc.html) {
return 404;
}
}
}
}
Then if you have an index.html file similar to this:
<html>
<body>
<!--# include file="$inc.html" -->
</body>
</html>
it will now include (via SSI) whatever page is requested. So for example /home would include home.html into index.html. This makes it easy to have a common style (headers and footers) without resorting to PHP or a framework.
It assumes home.html exists.
从列子不难看出 ssi的 的作用， 有点像jsp的include 标签 ，不同的是 ssi 引用的 页面 来自静态页面 ，是不经过后台的。
