控制緩存過期

通過Google網站管理員工具的PageSpeed分析器運行我的網頁後，它向我報告我的資源沒有被緩存。以下是我直接從H5BP獲取的.htaccess文件中的代碼。我是否正確地假設下面的過期設置正確，並且在我的實施中出現了問題，或者我是否必須爲每個文件名設置明確的到期期限，而不是對廣義的泛化進行設置？控制緩存過期

# ---------------------------------------------------------------------- 
# Expires headers (for better cache control) 
# ---------------------------------------------------------------------- 

# These are pretty far-future expires headers. 
# They assume you control versioning with filename-based cache busting 
# Additionally, consider that outdated proxies may miscache

# If you don't use filenames to version, lower the CSS and JS to something like 
# "access plus 1 week". 

<IfModule mod_expires.c> 
    ExpiresActive on 

# Perhaps better to whitelist expires rules? Perhaps. 
    ExpiresDefault       "access plus 1 month" 

# cache.appcache needs re-requests in FF 3.6 (thanks Remy ~Introducing HTML5) 
    ExpiresByType text/cache-manifest  "access plus 0 seconds"

看起來不錯。

要麼你沒有指定mod_expires安裝模塊（1百萬不）或其他一些.htaccess或httpd.conf指令禁用這些其他地方。請使用頁面速度工具抓取您的文件發送的實際標題，然後粘貼。

我很確定必須有另一個htaccess文件覆蓋它，因爲我與某人共享測試服務器。不過，我只是想確保我所擁有的是好的。謝謝！ – 2013-02-26 17:10:23

我有完全相同的.htaccess文件（甚至包括評論，例如「Thanks Remy」）。但是我也收到seo分析的消息，說瀏覽器緩存沒有被利用。如何檢查是否 a）我已安裝mod_expires並且 b）有重寫？ thx – 2016-12-18 13:51:37
