我是php的新手,我有兴趣使用清漆来提高网站性能。
我安装了varnish最新版本:4.0.2 varnish

我使用cookie命名(mp3list和phpsessionid)所以我无法缓存我的页面,
我用vcl和
$sub vcl_recv {
call normalize_req_url;
set req.http.Cookie = regsub(req.http.Cookie, "^;\s*", "");
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
# If the requested URL starts like "/cart.asp" then immediately pass it to the given
# backend and DO NOT cache the result ("pass" basically means "bypass the cache").
if (req.url ~ "^/playlist\.php$") {
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);
}
现在我用这个删除了mp3list,还有phpsessid就在那里,如何删除phpsessid

任何人都可以指导我如何绕过phpsessid并编辑VCL并有效使用清漆
预先谢谢你........

正如您注意到PHP会话和Varnish不能很好地混合,即phpsessions会破坏varnish中url的可缓存性,因为它使它们都是唯一的。
选项: 1.完全禁用php会话(怀疑这是一个真正的选择)。 2.只在您绝对需要的页面上启用php会话,以便其余的可以缓存。 3.将与会话相关的php逻辑拆分为单独的php文件,并将ESI包含在主页中。这将允许您部分缓存页面(非ESI位)。
