我在Varnish缓存服务器后面用Nginx安装了Magento,并且我使用的是this extension。
然而,我从来没有在缓存上得到一个命中:

X-Cache-Expires: Mon, 31 Mar 2008 10:00:00 GMT我理解原因是因为设置了cookie,所以Varnish将请求传递给Nginx,但我找不到它没有从请求中删除它们的原因(这应该根据我使用的default.vcl完成,该cookie是由模块提供的)

Magento正在返回一个响应,表明它不应该被缓存。所以varnish不会缓存它:
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0, s-maxage=0您需要返回公共缓存头(如果您愿意,可以使用正的max-age指令)
Cache-Control: public, max-age=600和/或具有将来日期的Expires报头。
此外,如果您使用的是default.vcl,在响应中出现Set-Cookie标头也会导致项目不被缓存:
# sub vcl_fetch {
# if (beresp.ttl <= 0s ||
# beresp.http.Set-Cookie || /* Look at this line */
# beresp.http.Vary == "*") {
# /*
# * Mark as "Hit-For-Pass" for the next 2 minutes
# */
# set beresp.ttl = 120 s;
# return (hit_for_pass);发布于 2014-06-04 20:11:31
您只需取消设置cookies,即可在.vcl文件中完成
sub vcl_recv {
unset req.http.cookie;
}
sub vcl_fetch {
unset beresp.http.set-cookie;
}
sub vcl_deliver {
unset resp.http.set-cookie;
}或
