光油：Cacheble但不緩存

如果我運行此命令光油：Cacheble但不緩存

varnishtop -i txurl

該請求是「cacheble」，而不是「緩存」。我看到「年齡= 0」（年齡保持清漆），如何編輯它？

這是我的PHP頁面請求

GET -Used http://example.com

你能否也請添加清漆配置？只有相關的部分。因爲這聽起來很像清漆配置問題。 – Silenteh 2012-02-18 12:37:31

好的，完成了。更新後 – sparkle 2012-02-18 14:18:44

您可以運行varnishlog，然後運行GET -Used http://example.com或curl -I http://example.com/，然後將varnishlog輸出粘貼到此處？ – 2012-02-19 06:16:37

大多數後端可能會返回一個cookie，因此varnish不會緩存內容。

關於它的更多資訊：Varnish-Cookies

還有你從LWP得到響應一些不一致的地方。事實上，我看到一個最大年齡標頭設置爲60秒，我沒有看到在任何地方的後端配置。

對原點的LWP請求也可以幫助調試問題。
