清漆饼干问题

Question

首先，抱歉我的英文不好，这不是我的自然语言。

我尝试为管理用户配置用于后端的清漆，我有一些问题需要登录和其他检查。

我对recv的配置，获取和哈希：

backend default { 
    .host = "127.0.0.1"; 
    .port = "8080"; 
} 

sub vcl_recv { 

    remove req.http.X-Forwarded-For; 
    set req.http.X-Forwarded-For = client.ip; 

    if (req.request == "POST"){ 
     return (pass); 
    } 

    # Grace mode 
    if (! req.backend.healthy) { 
      set req.grace = 30m; 
    } else { 
     set req.grace = 15s; 
    } 

    if(req.url ~ "^localhost$"){ 
    set req.http.host = "www.micasa.com"; 
    } 

    # Acces to system URL's is protected 
    if ((req.url ~ "^/server_status") || (req.url ~ "^/discover/varnish_server")) { 
     error 403 "Go away, please"; 
    } 

    # Delete all cookies except from user 

    if (!(req.url ~ "^/logout") && 
     !(req.url ~ "^/profile") && 
     !(req.url ~ "^/playlists") && 
     !(req.url ~ "^/users") && 
     !(req.url ~ "^/signup") && 
     !(req.url ~ "^/comments") && 
     !(req.url ~ "^/login") && 
     !(req.url ~ "^/remind")) 
     { 
       unset req.http.cookie; 
     } 

sub vcl_fetch { 

    # Grace mode 
    # https://www.varnish-cache.org/docs/trunk/tutorial/handling_misbehaving_servers.html#grace-mode 
    set beresp.grace = 30m; 

    # Saint mode 
    # https://www.varnish-cache.org/docs/trunk/tutorial/handling_misbehaving_servers.html#saint-mode 
    if (beresp.status == 500) { 
    set beresp.saintmode = 10s; 
    return (restart); 
    } 
    if (!(req.url ~ "^/login") && (req.request == "GET")){ 
     unset beresp.http.set-cookie; # To avoid caching of cookies 
    } 

    # Process ESIs if X-RUN-ESI is set. This will be stripped before being sent down to client. 
    if (beresp.http.X-RUN-ESI) { 
    set beresp.do_esi = true; 
    remove beresp.http.X-RUN-ESI; 
    } 

    # cache 404s and 301s for 5 minute 
    if (beresp.status == 404 || beresp.status == 301 || beresp.status == 500) { 
    set beresp.ttl = 15m; 
    return (deliver); 
    } 

    # cache images and static assets during 15m 
    if (req.url ~ "\.(png|gif|jpg|css|js|ico)") { 
    set beresp.ttl = 15m; 
    return (deliver); 
    } 


    # If X-VARNISH-TTL is set, use this header's value as the TTL for the varnish cache. 
    # Expires, cache-control, etc. will be passed directly through to the client 
    # Cribbed from http://www.lovelysystems.com/configuring-varnish-to-use-custom-http-headers/ 
    if (beresp.http.X-VARNISH-TTL) { 
    C{ 
     char *ttl; 
     /* first char in third param is length of header plus colon in octal */ 
     ttl = VRT_GetHdr(sp, HDR_BERESP, "\016X-VARNISH-TTL:"); 
     VRT_l_beresp_ttl(sp, atoi(ttl)); 
    }C 
    remove beresp.http.X-VARNISH-TTL; 
    return (deliver); 
    } 
sub vcl_deliver { 
    unset resp.http.x-url; # Optional 
    if (req.url ~ "\.(png|gif|jpg|css|js|ico|woff)") { 
     set resp.http.expires = "3600"; 
    } 

    #mikel 
    #remove resp.http.X-Powered-By; 
    remove resp.http.Server; 
    #remove resp.http.X-Varnish; 
    #remove resp.http.Via; 
    #remove resp.http.Age; 

} 

sub vcl_hash { 
    if (req.http.Cookie ~ "_micasa_session") { 
    hash_data(req.url); 
    hash_data(req.http.Cookie); 
     return (hash); 
    } 
} 

当我尝试与用户它的确定洛，但如果我以后刷新了同一页面，我失去了cookie，并立刻退出，也许问题在子vcl_recv？

感谢您的提前帮助。

您取消设置除定义页面以外的所有Cookie。您的网站登录几乎肯定会保存在cookie（会话cookie？）中。简单的方法是通过检查是否设置了标识登录用户的cookie来禁用登录用户的缓存。好的方法是使用ESI，以便所有用户的部分都被缓存。
