二、Web服务器处理

通过查看HTTP头，我们可以快速判断使用的客户端浏览器是否支持接受gzip压缩。

若发送的HTTP头中出现以下信息，则表明你的浏览器支持接受相应的gzip压缩：

# mod_gzip

<span <</span><span ifModule </span><span mod_gzip.c</span><span ></span><span 

mod_gzip_on Yes

mod_gzip_dechunk Yes

mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$

mod_gzip_item_include handler ^cgi-script$

mod_gzip_item_include mime ^text/.*

mod_gzip_item_include mime ^application/x-javascript.*

mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

</span><span <</span><span ifModule</span><span ></span>

DeflateCompressionLevel 6 #压缩率, 6是建议值.
