Apache上使用mod_deflate压缩网页输出

Posted by eDWARD at 17:06

配置mod_deflate模块

1. 因为我已经安装了mod_deflate模块，所以现在只需要配置apache的httpd.conf文件就可以了，就可以把css,javascript,html压缩70%左右。

   <location />
   # Insert filter
   SetOutputFilter DEFLATE 
   
   # Netscape 4.x has some problems…
   BrowserMatch ^Mozilla/4 gzip-only-text/html 
   
   # Netscape 4.06-4.08 have some more problems
   BrowserMatch ^Mozilla/4.0[678] no-gzip 
   
   # MSIE masquerades as Netscape, but it is fine
   # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html 
   
   # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.59
   # the above regex won’t work. You can use the following
   # workaround to get the desired effect:
   BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html 
   
   # Don’t compress images and other
   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 
   
   # Make sure proxies don’t deliver the wrong content
   #Header append Vary User-Agent env=!dont-vary 
   
   DeflateFilterNote ratio
   LogFormat ‘”%v %h %l %u %t “%r” %>s %b “%{Referer}i” “%{User-Agent}i”” (%{ratio}n)’ deflate 
   
   CustomLog logs/deflate_log deflate
   

   或者把SetEnvIfNoCase替换成

   AddOutputFilterByType DEFLATE text/*
   AddOutputFilterByType DEFLATE application/ms* application/vnd* application/postscript 
   
   

   不管哪种方法都是为了把某些不需要压缩的文件排出，这样被压缩过的网页就会比没有压缩的网页小很多，传输速度也会变快，就是说打开网页会快一些。

感谢大黄的提醒，虽然在编译Apache的时候编译过这个模块，但当时还不知道是做什么用的……现在可以给网页提速了，果然是个好东东。
