使用Apache模块mod_deflate加快页面打开速度

mod_deflate 模块提供了DEFLATE 输出过滤器，允许服务器在将输出内容发送到客户端以前进行压缩，以节约带宽。

修改httpd.conf

1.使用此模块
LoadModule deflate_module modules/mod_deflate.so

2.在conf文件底下加上

#set deflate modules
#
#DeflateCompressionLevel 9    #设置压缩率
#AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-httpd-php
#AddOutputFilter DEFLATE css js
#             

 

#以上设置，经过测试后感觉不太好，没有对css和js文件进行压缩。

 

SetOutputFilter DEFLATE

AddOutputFilterByType DEFLATE text/html text/plain text/xml
AddOutputFilter DEFLATE css       #压缩css文件
AddOutputFilter DEFLATE js          #压缩js文件

#BrowserMatch ^Mozilla/4 gzip-only-text/html
#BrowserMatch ^Mozilla/4\.0[678] no-gzip
#BrowserMatch \bMSIE !no-gzip !gzip-only-text/html     #针对不同浏览器的配置，这里用处不大

# Don't compress images                                           #对照片文件不进行压缩处理
SetEnvIfNoCase Request_URI (?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI (?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .pdf$ no-gzip dont-vary
#SetEnvIfNoCase Request_URI .(css|js)$ no-gzip dont-vary

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary

DeflateFilterNote Input input_info                                 #设置日志输出！         
DeflateFilterNote Output output_info
DeflateFilterNote Ratio ratio_info
LogFormat '"%r" %{output_info}n/%{input_info}n (%{ratio_info}n%%)' deflate
CustomLog logs/deflate_log.log deflate

 

 以下是日志输出 deflate_log.log ：

可以看到除了图片jpg格式文件外，其他的jsp,css,js 等都进行了压缩处理！
