apache使用gzip压缩
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
<IfModule mod_deflate.c> # 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 </IfModule>
重启apache进行测试
测试代码如下:
1 <html>
2 <body>
3 </body>
4 <div >1234</div>
5 <input type="button" value="ajax请求php页面" onclick="display()" />
6 <script src="./js/zepto.min.js" type="text/javascript" charset="utf-8"></script>
7 <script type="text/javascript" charset="utf-8">
8 function display()
9 {
10 $.ajax(
11 {
12 type:"post",
13 url:"newfile.php",
14 data:"des=hello",
15 success:function(msg){alert(msg);}
16 }
17 );
18 }
19 </script>
20 </body>
21 </html>未开启:gzip情况下zepto.min.js回送的信息如下:
Request URL:http://localhost/zybook/mytest/js/zepto.min.js Request Method:GET Status Code:200 OK Request Headersview source Accept:*/* Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:zh-CN,zh;q=0.8 Cache-Control:no-cache Connection:keep-alive Host:localhost Pragma:no-cache Referer:http://localhost/zybook/mytest/zepto.html User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.60 Safari/537.1 Response Headersview source Accept-Ranges:bytes Connection:Keep-Alive Content-Length:24014 Content-Type:application/javascript Date:Mon, 06 Aug 2012 02:58:22 GMT ETag:"1b000000010dca-5dce-4c65a8edc6347" Keep-Alive:timeout=5, max=96 Last-Modified:Fri, 03 Aug 2012 11:09:13 GMT Server:Apache/2.2.22 (Win64) PHP/5.3.13
开启gzip得到的回送信息
Request URL:http://localhost/zybook/mytest/js/zepto.min.js Request Method:GET Status Code:200 OK Request Headersview source Accept:*/* Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:zh-CN,zh;q=0.8 Cache-Control:no-cache Connection:keep-alive Host:localhost Pragma:no-cache Referer:http://localhost/zybook/mytest/zepto.html User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.60 Safari/537.1 Response Headersview source Accept-Ranges:bytes Connection:Keep-Alive Content-Encoding:gzip Content-Length:8622 Content-Type:application/javascript Date:Mon, 06 Aug 2012 02:59:51 GMT ETag:"1b000000010dca-5dce-4c65a8edc6347" Keep-Alive:timeout=5, max=87 Last-Modified:Fri, 03 Aug 2012 11:09:13 GMT Server:Apache/2.2.22 (Win64) PHP/5.3.13 Vary:Accept-Encoding
