Magento没有打清漆缓存

Question

I have setup a Magento installation with Nginx behind a Varnish cache server and I'm using this extension .

However, I never get a hit on cache:

HTTP/1.1 200 OK
Server: nginx/1.1.19
Content-Type: text/html; charset=UTF-8

I understand the reason is because of the cookies being set, so Varnish passes the request on to Nginx, but I can't find the reason it's not removing them from the request (this should be done according to the default.vcl which I'm using the one provided by the module)

Answer 1

Magento is returning a response indicating it that should not be cached. So varnish isn't caching it:

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0, s-maxage=0

You need to return public cache headers (with a positive max-age directive if you like)

Cache-Control: public, max-age=600

and/or an Expires header with a date in the future.

Also, the presence of Set-Cookie headers in the response, if you're using the default.vcl, would also result in the item not being cached:

# 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);

Answer 2

You just have to unset the cookies only and you are done in your .vcl file

sub vcl_recv {
    unset req.http.cookie;
}

sub vcl_fetch {
    unset beresp.http.set-cookie;
}

sub vcl_deliver {
 unset resp.http.set-cookie;
}
