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。
