wtxnpw

Apache下载：http://httpd.apache.org/download.cgi


../conf/httpd.conf
分别搜索关键字ServerTokens和ServerSignature，修改：
ServerTokens OS 修改为 ServerTokens ProductOnly
ServerSignature On 修改为 ServerSignature Off

上边一段的说明<IfModule mod_deflate.c>中
SetOutputFilter DEFLATE    #必须的，就像一个开关一样，告诉apache对传输到浏览器的内容进行压缩
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary #设置不对后缀gif，jpg，jpeg，png的图片文件进行压缩
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary #同上，就是设置不对exe，tgz，gz。。。的文件进行压缩
SetEnvIfNoCase Request_URI .(?:pdf|mov|avi|mp3|mp4|rm)$ no-gzip dont-vary
AddOutputFilterByType DEFLATE text/* #设置对文件是文本的内容进行压缩，例如text/html  text/css  text/plain等
AddOutputFilterByType DEFLATE application/ms* application/vnd* application/postscript application/javascript application/x-javascript #这段代码你只需要了解application/javascript application/x-javascript这段就可以了，这段的意思是对javascript文件进行压缩
AddOutputFilterByType DEFLATE application/x-httpd-php application/x-httpd-fastphp #这段是告诉apache对php类型的文件进行压缩
BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.x 有一些问题，所以只压缩文件类型是text/html的
BrowserMatch ^Mozilla/4.0[678] no-gzip # Netscape 4.06-4.08 有更多的问题，所以不开启压缩
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # IE浏览器会伪装成 Netscape ，但是事实上它没有问题
