apache使用gzip压缩

wojkxlq

　　打开http.conf文件,首先开启gzip模块:



LoadModule deflate_module modules/mod_deflate.so

　　
　　然后,配置何时使用gzip压缩




# 压缩等级 9
DeflateCompressionLevel 9
# 压缩类型 html、xml、php、css、js
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-javascript application/x-httpd-php
AddOutputFilter DEFLATE js css


　　
　　重启apache进行测试
　　测试代码如下:

9 {
10     $.ajax(
11         {
12             type:"post",
13             url:"newfile.php",
14             data:"des=hello",
15             success:function(msg){alert(msg);}
16         }
17         );
