Question

好吧，我真的不知道如何提出问题，但我的问题或者至少我认为问题是这样的：

我正在处理的博客加载速度非常慢，所以我做了正常的事情以加快速度，例如添加gzip和禁用所有插件等等，但它没有帮助。所以我查看了Firebug中发送的标题，并注意到页面的原始请求正在进行，而其余请求正常加载。

以下是给定页面的响应/请求标头：

请求标题

Host:               dev.mydomain.com
User-Agent:         Mozilla/5.0... ...Firefox/3.6.17
Accept:             text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language:    en-us,en;q=0.5
Accept-Encoding:    gzip,deflate
Accept-Charset:     ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive:         115
Connection:         keep-alive
Referer:            http://dev.mydomain.com/blog/2011/05/06/hello-world/
Cookie:             Cookie data...

响应标题

Content-Encoding:   gzip
Content-Length:     4981

显然这里出现了问题，因为没有缓存，连接设置为关闭，过期时间是30年前。

这是我的.htaccess文件，我设置过期标题等。

的.htaccess

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/x-javascript

# Or, compress certain file types by extension:
<Files *.html|*.php>
SetOutputFilter DEFLATE
</Files>

RewriteCond %{REQUEST_FILENAME} !-f  
RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d

## Ignore CSS, Scripts and Images
RewriteRule !\.(xml|swf|js|ico|gif|jpg|png|css|htc)$ index.php [L]

任何帮助，如果非常感激。

BTW，我在CentOS 5上运行PHP 5.2.10 / MySQL 5.1上的WordPress 3.1.1。*

我正在与同样的问题作斗争，我发现的一件事是你的.htaccess文件只有你的网站主机提供的权限一样好。您是托管自己的网站还是拥有网站托管公司？

如果您要托管自己的站点，则需要确保正确设置“允许覆盖”指令，以便.htaccess规则可以正常工作。更好的是，设置httpd.config文件也可以为你完成工作。

但是，如果您与一家网站托管公司合作，那么您需要向他们询问您可以使用哪些指令（您编写的那些.htaccess规则）？如果您的webhost将Allow Override设置为NONE，则将忽略.htaccess文件。

我搜索到的所有地方都表明，在遥远的未来设置的Expires标头是最好的：当它在过去（1981年11月）设置时，它会强制浏览器每次都获取新的页面/图像。

我建议的最后一件事是仔细检查你的.htaccess规则，这里有一个对你有用的集合作为起点：

#BEGIN htaccess
#Protect the htaccess file
<Files .htaccess>
Order Allow,Deny
Deny from all
</Files>

#Protect the htaccess file
<Files wp-config.php>
Order Allow,Deny
Deny from all
</Files>

# Disable directory browsing
Options All -Indexes

# Enable the following of symlinks
Options +FollowSymLinks

<IfModule mod_headers.c>
# No ETags, No Pragma
Header unset Pragma
Header unset ETag
# Make sure proxies deliver correct content
Header append Vary User-Agent env=!dont-vary
# Ensure proxies deliver compressed content correctly
Header append Vary Accept-Encoding
</IfModule>

# Set up Cache Control headers
ExpiresActive On
# Default - Set http header to expire everything 1 week from last access, set must-revalidate
ExpiresDefault A604800
Header append Cache-Control: "max-age=3600, must-revalidate"
# Apply a customized Cache-Control header to frequently-updated files
<FilesMatch "^(test¦eval)\.html$">
ExpiresDefault A1
Header unset Cache-Control:
Header append Cache-Control: "no-cache, must-revalidate"
</FilesMatch>
<FilesMatch "^robots\.txt$">
ExpiresDefault A7200
</FilesMatch>

ExpiresByType image/x-icon A14515200

# Set up caching on media files for 1 month
<FilesMatch "\.(gif|jpg|JPG|jpeg|png|PNG|swf)$">
  ExpiresDefault A2419200
</FilesMatch>

# Set up caching on commonly updated files 1 month
<FilesMatch "\.(xml|txt|html|js|css)$">
  ExpiresDefault A2419200
</FilesMatch>

<FilesMatch "\.(ico|gif|jpg|JPG|jpeg|png|PNG|css|js|html?|xml|txt)$">
FileETag None
</FilesMatch>

<IfModule mod_deflate.c>
<FilesMatch "\.(js|css|text|html)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>

希望这有所帮助 - 祝你好运！
