使用Apache子產品mod_deflate加快頁面打開速度

mod_deflate 子產品提供了<code>deflate</code>輸出過濾器，允許伺服器在将輸出内容發送到用戶端以前進行壓縮，以節約帶寬。

修改httpd.conf

1.使用此子產品 

loadmodule deflate_module modules/mod_deflate.so 

2.在conf檔案底下加上

#deflatecompressionlevel 9    #設定壓縮率

#addoutputfilterbytype deflate text/html text/plain text/xml application/x-httpd-php

#addoutputfilter deflate css js

#&lt;/ifmodule&gt;             

#以上設定，經過測試後感覺不太好，沒有對css和js檔案進行壓縮。

&lt;location /&gt;

setoutputfilter deflate

addoutputfilterbytype deflate text/html text/plain text/xml

addoutputfilter deflate css       #壓縮css檔案

addoutputfilter deflate js          #壓縮js檔案

#browsermatch ^mozilla/4 gzip-only-text/html

#browsermatch ^mozilla/4\.0[678] no-gzip

#browsermatch \bmsie !no-gzip !gzip-only-text/html     #針對不同浏覽器的配置，這裡用處不大

# don't compress images                                           #對照片檔案不進行壓縮處理

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

&lt;/location&gt;

deflatefilternote input input_info                                 #設定日志輸出！         

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

 以下是日志輸出 deflate_log.log ：
