PHP 缓存控制

我最近开始对我的网站进行一些缓存控制，但似乎有些功能因此停止工作。我的 PHP 内容不再更新。在 Chrome 网络工具中，我可以看到一些 PHP 脚本请求大小（来自缓存）。我尝试刷新页面，但仍然没有更新。只有当我从 Chrome 中删除整个缓存数据时，它才会更新。我尝试删除我在 .htaccess 中所做的操作，但它仍然没有更新。我如何声明 PHP 脚本不应保存在缓存中？目前，javascript 文件使用带有 GET 方法的 ajax 来更新这些 PHP 脚本的一些不再更新的 HTML 文本。

我的.htaccess：

AddDefaultCharset UTF-8

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 month"

# Media: images, video, audio
  ExpiresByType image/gif                 "access plus 1 year"
  ExpiresByType image/png                 "access plus 1 year"
  ExpiresByType image/jpg                 "access plus 1 year"
  ExpiresByType image/jpeg                "access plus 1 year"

  ExpiresByType video/mp4                 "access plus 1 year"

ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresByType text/html "access plus 2 days"

# CSS and JavaScript
  ExpiresByType text/css                  "access plus 1 month"
  ExpiresByType application/javascript    "access plus 1 year"
  ExpiresByType text/javascript           "access plus 1 year"

# Webfonts

  ExpiresByType font/opentype             "access plus 1 year"
  ExpiresByType application/x-font-woff   "access plus 1 year"
  ExpiresByType image/svg+xml             "access plus 1 year"

这是我的缓存配置，效果非常好：

# MOD_DEFLATE COMPRESSION
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application$

# DEFLATE NOT COMPATIBLE BROWERS
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

# NOT CHACHING IF ALREADY CACHED
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip

# EXPIRE HEADERS
<IfModule mod_expires.c>
ExpiresActive On
#Images
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
AddType image/x-icon .ico
ExpiresByType image/ico "access plus 1 year"
ExpiresByType image/icon "access plus 1 year"
ExpiresByType image/x-icon "access plus 1 year"
#Elements
ExpiresByType application/xhtml+xml "access plus 1 week"
ExpiresByType text/html "access plus 1 week"
ExpiresByType text/css "access plus 1 week"
ExpiresByType application/javascript "access plus 1 week"
ExpiresByType text/x-javascript "access plus 1 week"
#Others
ExpiresDefault "access plus 1 month"
</IfModule>

# CACHE-CONTROL HEADERS
<IfModule mod_headers.c>
<FilesMatch "\\.(ico|jpe?g|png|gif|swf|gz|ttf)$">
Header set Cache-Control "max-age=2797200, public"
</FilesMatch>
<FilesMatch "\\.(css)$">
Header set Cache-Control "max-age=2797200, public"
</FilesMatch>
<FilesMatch "\\.(js)$">
Header set Cache-Control "max-age=2797200, private"
</FilesMatch>
<filesMatch "\\.(html|htm)$">
Header set Cache-Control "max-age=86400, public"
</filesMatch>
# Disable caching for scripts and other dynamic files
<FilesMatch "\.(pl|php|cgi|spl|scgi|fcgi)$">
Header unset Cache-Control
</FilesMatch>
</IfModule>

除动态内容外，所有内容都经过缓存和压缩。

基于 http://www.seomix.fr/guide-htaccess-performances-et-temps-de-chargement/

要强制 php 标头，你可以这样做

<FilesMatch "\.php$">
     Header unset ETag
     Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
     Header set Pragma "no-cache"
     Header set Expires "Sat, 2 Aug 1980 15:15:00 GMT"

     ExpiresActive On
     ExpiresDefault "access plus 0 seconds"
</FilesMatch>
