清漆刷新

期間擔任老物件我怎樣才能在獲取過期的對象或最大 輸出連接的服務的舊對象？清漆刷新

I¹ve配置在兩個vcl_recv作爲vcl_fetch寬限期。

我甚至試圖用聖人模式給我回一個³old²緩存的對象。

有人可以給我在這個問題上幫助？

sub vcl_recv { 

# Purge through http 
if (req.request == "PURGE") { 
if (!client.ip ~ purge) { 
error 405 "Not allowed."; 
} 
ban("req.url ~ " + req.url); 
error 200 "Purged."; 
} 

# Unset all cookies available 
if (req.http.cookie) { 
unset req.http.cookie; 
} 

if (req.request != "GET" && req.request != "HEAD") { 
/* We only deal with GET and HEAD by default */ 
return (pass); 
} 

# Adding Grace period in case backend lags 
set req.grace = 3d; 
return (lookup); 
} 
.... 
sub vcl_fetch { 
set beresp.grace = 4d; 
set beresp.saintmode = 50s; 
set beresp.ttl = 30s; 
return (deliver); 
}

由於這清漆郵件列表上已經要求/建議，請檢查您的擴展VCL，看看您的網頁被緩存。如果是這種情況，請提供varnishlog調用的輸出。 – Mojah 2012-02-07 13:49:26

添加了請求的varnislog條目。第一個顯示我很好。第二部分是過期的。該req.grace設爲30秒//該beresp.ttl設爲30秒//該beresp.grace被設置爲40秒 – 2012-02-07 14:31:40

這是一個有趣的問題。

從DOC

當幾個客戶端請求相同的頁面上光油將發送 一個請求到後端，並把其他人保持，同時從後端獲取 一個副本。

因此，即使您啓用了寬限期，在任何時間點都會有一個客戶端被阻止。格雷斯告訴Varnish，你可以用陳舊的內容爲所有其他n-1客戶提供服務，直到第一個人回來刷新一些內容爲止。有沒有辦法疏通一個傢伙[技術上採用了異步獲取是不可能的，因爲這種]

看看這個漂亮的article我想你實際上需要的是下一個發行計劃的功能，我希望
