Caching 第四次击中未遂头球？

是否有人更新了Varnish 4的命中未命中标题

我找到的最后一个是版本3

寻找这些：

set beresp.http.X-Cacheable=“否：不可缓存”；“否：获取会话”；
“否：缓存控制=专用”；“是”

以及其他可能有用的调试输出，说明请求丢失的原因。
是的，：

将所需标题的varnish 3版本直接翻译为varnish 4：

sub vcl_backend_response {

    if (bereq.http.Cookie ~ "(UserID|_session)") {
        set beresp.http.X-Cacheable = "NO:Got Session";
        set beresp.uncacheable = true;
        return (deliver);

    } elsif (beresp.ttl <= 0s) {
        # Varnish determined the object was not cacheable
        set beresp.http.X-Cacheable = "NO:Not Cacheable";

    } elsif (beresp.http.set-cookie) {
        # You don't wish to cache content for logged in users
        set beresp.http.X-Cacheable = "NO:Set-Cookie";
        set beresp.uncacheable = true;
        return (deliver);

    } elsif (beresp.http.Cache-Control ~ "private") {
        # You are respecting the Cache-Control=private header from the backend
        set beresp.http.X-Cacheable = "NO:Cache-Control=private";
        set beresp.uncacheable = true;
        return (deliver);

    } else {
        # Varnish determined the object was cacheable
        set beresp.http.X-Cacheable = "YES";
    }

    # ....

    return(deliver);
}

子vcl\u后端\u响应{
if（bereq.http.Cookie~“（UserID |_session）”）{
设置beresp.http.X-Cacheable=“NO:Got Session”；
设置beresp.uncacheable=true；
归还（交付）；
}elsif（beresp.ttl）我更喜欢这些（根据我最初问题中的直接链接）：
set-beresp.http.X-Cacheable=“NO:Not-Cacheable”；“NO:Got Session”；“NO:Cache Control=private”；“YES”；
谢谢！省略
返回（deliver）是否明智
？为什么？因为它是默认值，并且允许处理下面的其他
子vcl\u backend\u响应。
sub vcl_backend_response {

    if (bereq.http.Cookie ~ "(UserID|_session)") {
        set beresp.http.X-Cacheable = "NO:Got Session";
        set beresp.uncacheable = true;
        return (deliver);

    } elsif (beresp.ttl <= 0s) {
        # Varnish determined the object was not cacheable
        set beresp.http.X-Cacheable = "NO:Not Cacheable";

    } elsif (beresp.http.set-cookie) {
        # You don't wish to cache content for logged in users
        set beresp.http.X-Cacheable = "NO:Set-Cookie";
        set beresp.uncacheable = true;
        return (deliver);

    } elsif (beresp.http.Cache-Control ~ "private") {
        # You are respecting the Cache-Control=private header from the backend
        set beresp.http.X-Cacheable = "NO:Cache-Control=private";
        set beresp.uncacheable = true;
        return (deliver);

    } else {
        # Varnish determined the object was cacheable
        set beresp.http.X-Cacheable = "YES";
    }

    # ....

    return(deliver);
}
