mod_deflate配置详解
mod_deflate配置详解
先放上我服务器上的设置
<ifmodule mod_deflate.c>
DeflateCompressionLevel 9
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-httpd-php
AddOutputFilter DEFLATE html htm xml php css js
</ifmodule>
DeflateCompressionLevel 9
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-httpd-php
AddOutputFilter DEFLATE html htm xml php css js
</ifmodule>
以下是我摘录apache手册中关于mod_deflate的部份
仅仅压缩少数几种类型
AddOutputFilterByType DEFLATE text/html text/plain text/xml
以下允许压缩更多内容的配置更加复杂。除非你明白所有的配置细节，否则请不要使用。
Compress everything except images
<location />
# 开启压缩
SetOutputFilter DEFLATE
# Netscape 4.x 有一些问题...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 有更多的问题
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# MSIE 会伪装成 Netscape ，但是事实上它没有问题
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# 不压缩图片
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary
# 确保代理不会发送错误的内容
Header append Vary User-Agent env=!dont-vary
# 开启压缩
SetOutputFilter DEFLATE
