如何使用 varnish 缓存和名为 mp3list 和 phpsessionid 的 set-cookie

我是 php 新手，我有兴趣使用 varnish 来提高网站性能。

我安装的是Varnish的最新版本：4.0.2Varnish

mp3list我使用名为 (和)的 cookie phpsessionid，因此无法缓存我的页面。我使用 vcl 进行以下操作：

$sub vcl_recv {
  call normalize_req_url;
set req.http.Cookie = regsub(req.http.Cookie, "^;\s*", "");
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
# If the requested URL starts like "/cart.asp" then immediately pass it to the given
# backend and DO NOT cache the result ("pass" basically means "bypass the cache").
if (req.url ~ "^/playlist\.php$") {
   return (pass);
   }
}
sub vcl_backend_response {
 # Happens after we have read the response headers from the backend.
 #
 # Here you clean the response headers, removing silly Set-Cookie headers
 # and other mistakes your backend does.
 if (beresp.http.Set-Cookie)
 {
  set beresp.http.Set-Cookie = regsub(beresp.http.Set-Cookie, "^php","");
  if (beresp.http.Set-Cookie == "")
    {
        unset beresp.http.Set-Cookie;
    }
  }
 unset beresp.http.Cache-Control;
 set beresp.http.Cache-Control = "public";
 }
 sub vcl_deliver {
 # Happens when we have all the pieces we need, and are about to send the
 # response to the client.
 #
 # You can do accounting or modifying the final object here.
 # Was a HIT or a MISS?

 if ( obj.hits > 0 )
 {
  set resp.http.X-Cache = "HIT";
 }
 else
 {
  set resp.http.X-Cache = "MISS";
 } 
 # And add the number of hits in the header:
  set resp.http.X-Cache-Hits = obj.hits;
 }
 sub normalize_req_url {
 # Strip out Google Analytics campaign variables. They are only needed
 # by the javascript running on the page
 # utm_source, utm_medium, utm_campaign, gclid, ...
 if(req.url ~ "(\?|&)(gclid|cx|ie|cof|siteurl|zanpid|origin|utm_[a-z]+|mr:[A-z]+)=") {
    set req.url = regsuball(req.url, "(gclid|cx|ie|cof|siteurl|zanpid|origin|utm_[a-z]+|mr:[A-               z]+)=[%.-_A-z0-9]+&?", "");
  }
  set req.url = regsub(req.url, "(\?&?)$", "");
  }
  sub vcl_hash {
  hash_data(req.url);
  if (req.http.host) {
  hash_data(req.http.host);
  } else {
  hash_data(server.ip);
  }
  hash_data(req.http.Cookie);
  }

现在我使用它删除了 mp3list，但仍然phpsessid存在，我该怎么做才能删除 phpsessid？

有人知道如何绕过 phpsessid 并编辑 VCL，以有效地使用 varnish 吗？

我不太清楚你想要什么，你想删除 PHPSESSID cookie？这里有一个指南； https://www.varnish-cache.org/trac/wiki/VCLExampleRemovingSomeCookies
