如何设置两个后端的清漆？

Question

我已经安装了Apache和Tomcat，并希望在它们面前安装Varnish，静态转到Apache，动态转到Tomcat（所有/ static / * url转到Apache，应该由Varnish缓存，其他网址转到Tomcat）的

如何配置清漆？

backend static {
  .host = "127.0.0.1";
  .port = "8080";
}
backend dynamic {
  .host = "127.0.0.1";
  .port = "8081";
}
sub vcl_recv {
 if (req.url ~ "^/static/") { # How to determine which backend to go to, and cache it?
    return (lookup);         # return (static.lookup)?
 } else {
    return (lookup);
 }
 return (lookup);
}

Answer 1

根据Varnish documentation，使用

set req.backend = static;

等等。
