运行资产:预编译rake任务时,会创建应用资源的gzip压缩版本。根据资产管道的Rails指南,您可以配置您的Web服务器(在我的情况下是Apache 2.2)来提供这些预压缩文件,而不是让Web服务器完成工作。
我无法弄清楚如何配置mod_deflate以便提供这些文件而不是双重压缩然后提供?
我通过httpd.conf启用了mod_deflate:
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
我已经将rails指南上的代码转换为公共/资产中的.htaccess:
# Some browsers still send conditional-GET requests if there's a
# Last-Modified header or an ETag header even if they haven't
# reached the expiry date sent in the Expires header.
Header unset Last-Modified
Header unset ETag
FileETag None
# RFC says only cache for 1 year
ExpiresActive On
ExpiresDefault "access plus 1 year"
# Serve gzipped versions instead of requiring Apache to do the work
RewriteEngine on
RewriteCond %{REQUEST_FILENAME}.gz -s
RewriteRule ^(.+) $1.gz [L]
# without it, Content-Type will be "application/x-gzip"
<FilesMatch .*\.css.gz>
ForceType text/css
</FilesMatch>
<FilesMatch .*\.js.gz>
ForceType text/javascript
</FilesMatch>
任何想法如何正确设置?

首先,您不希望mod_deflate在此处运行。所以在您的资产.htaccess文件中添加:
SetEnv no-gzip
这应该会关闭资产的mod_deflate。
其次,我讨厌不同意铁路人员,但我认为他们的资产存在一些不足.htaccess配方。最上面的部分很好,但是对于RewriteEngine而言,我有:
RewriteEngine on
# Make sure the browser supports gzip encoding before we send it
RewriteCond %{HTTP:Accept-Encoding} \b(x-)?gzip\b
RewriteCond %{REQUEST_URI} .*\.(css|js)
RewriteCond %{REQUEST_FILENAME}.gz -s
RewriteRule ^(.+) $1.gz [L]
# without it, Content-Type will be "application/x-gzip"
# also add a content-encoding header to tell the browser to decompress
<FilesMatch \.css\.gz$>
ForceType text/css
Header set Content-Encoding gzip
</FilesMatch>
<FilesMatch \.js\.gz$>
ForceType application/javascript
Header set Content-Encoding gzip
</FilesMatch>
