网页gzip压缩

客户端发送请求，服务端先压缩数据再响应。
可以在.htaccess里面做如下配置
#GZIP压缩模块配置
<ifmodule mod_deflate.c>
#启用对特定MIME类型内容的压缩
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
</ifmodule> apache要开启deflate_module、filter_module模块配置成功的话，响应头会有Contet-Encoding: gzip字段
