//Search Engine Optimization
The modularized site as written has a number of benefits, starting with the fact that it will be easier to maintain and expand as needed.
//模块化站点 维护 扩展
mod_rewrite is a tool that lets you instruct the server that when the user goes to one URL, the server should provide another resource.
mod_rewrite makes use of regular expressions, so the matching pattern and resulting actual URL can be as complex as needed.
Two ways to change Apache's behavior
0-edit the primary Apache configuration file
1-create directory-specific files
// 全局配置文件 目录相关文件
The primary configuration file is httpd.conf, found within a conf directory, and it dictates how the entire Apache Web server runs(where the httpd.conf file is on your system will depend on many things). An .htaccess file(pronounced “H-T access”) is placed within a Web directory and is used to affect how Apache behaveswithin just that folder and subfolders.Generally speaking, it’s preferable to make changes in the httpd.conf file, since this file needs to be read only by the Web server each time the server is started. Conversely, .htaccess files must be readby the Web server once for every request to which an .htaccess file might apply. For example, if youhave www.example.com/somedir/.htaccess, any request to www.example.com/somedir/whatever requires reading the .htaccess file, as well as reading an .htaccess file that might exist in www.example.com/. On the other hand, in shared hosting environments, individual users are not allowed to customize the entire Apache configuration, but they may be allowed to use .htaccess to make changes that only affect their sites. And changes to the primary configuration file do require restarting Apache to take effect.
