如何設置兩個後端的清漆？

Question

我已經安裝了Apache和Tomcat，並希望在它們前面安裝Varnish，靜態去Apache和動態去Tomcat（所有/靜態/ *網址去Apache，應該由Varnish緩存，其他網址去tomcat ）。

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

按Varnish documentation，使用

set req.backend = static; 

等。
