我试图启用Apache 2.2.15和5.3.3的输出压缩，但由PHP生成的网页不压缩:(
我的deflate.conf：
[user@host conf.d]# cat deflate.conf <IfModule mod_deflate.c> AddOutputFilterByType DEFLATE application/x-httpd-php AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE text/javascript AddOutputFilterByType DEFLATE image/svg+xml AddOutputFilterByType DEFLATE image/x-icon AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript DeflateCompressionLevel 9 # Browser specific settings BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html BrowserMatch \bOpera !no-gzip # Setup custom deflate log DeflateFilterNote Input instream DeflateFilterNote Output outstream DeflateFilterNote Ratio ratio LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate # Example of log file CustomLog logs/deflate_log DEFLATE 并在用于日志logging的vhostconfiguration文件中string：
CustomLog logs/vhost/deflate_log deflate
而我在日志中看到：

哪里不对？
这个答案给出了可以用mod_deflate在Apache 2.2中popup的问题的最佳总结。 解决方法是使用filter_module ＆ deflate_module来代替：
# Declare a "gzip" filter, it should run after all internal filters like PHP or SSI FilterDeclare gzip CONTENT_SET # "gzip" filter can change "Content-Length", can not be used with range requests FilterProtocol gzip change=yes;byteranges=no # Enable "gzip" filter if "Content-Type" contains "text/html", "text/css" etc. FilterProvider gzip DEFLATE resp=Content-Type $text/html FilterProvider gzip DEFLATE resp=Content-Type $text/css FilterProvider gzip DEFLATE resp=Content-Type $text/javascript FilterProvider gzip DEFLATE resp=Content-Type $application/javascript FilterProvider gzip DEFLATE resp=Content-Type $application/x-javascript # Add "gzip" filter to the chain of filters FilterChain gzip
