Php Varnish一直缺少缓存,cookies?

有人能给我解释一下为什么会发生这种情况,以及我应该改变什么吗
谢谢 这是因为谷歌分析。即使您的Web应用程序不使用cookies,您的分析JavaScript也会使用cookies。结果是一样的,Varnish会将请求传递到后端,并避免使用它的缓存 要解决此问题,请定义您的Web应用程序的URL,其中您必须使用cookie(例如管理面板),而您不需要使用cookie(此处您可以忽略Google Analytics的要求。大多数Web分析工具只需要浏览器和JavaScript之间的cookie) 下面,您可以看到一个清漆配置文件的示例。有趣的是,对于网站的非管理部分:发送的cookie以及一些新内容的浏览器请求标题将被删除
sub vcl_recv {
# regex to find all URLs where cookies are required
if (req.url ~ "^/admin/") {
# administration panel
set req.http.admin = 1;
} else {
# public web site, ignore client request for fresh content, remove cookies
unset req.http.Cache-Control;
unset req.http.Max-Age;
unset req.http.Pragma;
unset req.http.Cookie;
}
...
}
sub vcl_fetch {
if (req.http.admin == 1) {
# administration panel
return (hit_for_pass);
} else {
# public web site, not allowed to set cookies
unset beresp.http.Set-Cookie;
...
}
...
}
您可以使用
varnishlog
命令行工具来观察Varnish在处理每个请求时正在做什么。例如,您可以查看是否有任何cookie正在拆分
我感觉可能是另一台计算机上的用户代理稍有不同。Varnish在键中包含此值(如果已知)。我们的vcl\u recv
中有一条规则:
set req.http.User-Agent = "";
这为我们解决了一个类似的问题。默认情况下,以下代码是否不处理google cookie?#Remove拥有_js和Google Analytics Cookie。设置req.http.Cookie=regsuball(req.http.Cookie,(^ |;\s*)(uuu[a-z]+| has_js)=[^;]*,”);从外观上看,这确实是一个有效的正则表达式来去除那些cookies。但从清漆日志的输出来看,这并没有发生。有没有可能在其中一个包含中触发了返回(pass)或返回(pipe)?您已经粘贴了响应头,但我缺少一些包含脚本设置的expire值。我假设ttl设置为默认的40秒。也许在vcl_fetch中禁用magicmarker是个好主意,并在进行一些测试时观察年龄的变化。没有包含返回(仅适用于cpanel/whm URL)。没有区别。。可能是什么…:(在这个解决方案中,IE浏览器可能会有问题。。如果(req.http.User-Agent~“MSIE”){set req.http.User-Agent=“MSIE”;}或者{set req.http.User-Agent=“Mozilla compatible”;}对不起,请用英语说
set req.http.User-Agent = "";
