Question

我在页面http://www.okw-rutex.pl/上测试此站点包含js文件文件的清漆缓存 - http://miejsce.eu/shared,4980,101.js

这是此文件的标题

在symfony控制器中我使用缓存注释 -

@Cache(expires="1 day",public=true, maxage="86400")

在varnish配置部分返回不可缓存是

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

我怎样才能打开清漆缓存？

如果我用F5刷新页面（不发送Cache-Control：max-age = 0）还有

X-Cache:MISS
X-Cacheable:NO:Not Cacheable

如果是完全清漆配置

但从配置中删除日志部分允许清除缓存HIT。应该如何查看没有缓存信息的sub vcl_deliver？

Answer 1

在将对象写入缓存之前调用

vcl_backend_response，因此您在进入缓存之前修改响应。这意味着您没有看到陈旧的响应标头。请将您的诊断转移到vcl_deliver。

清漆不可缓存的symfony
