How to Use AllowOverride and Options of apache

The AllowOverride parameter indicates whether the Apache server is located. the htacess file is used as the configuration file. If it is set to none, the server will ignore it. if the htacess file is set to All, All. all commands in the htaccess file will be overwritten. For AllowOverride, you can also specify the following types of commands that can be overwritten.

Generally, when the Apache rewrite module is used to rewrite the URL, the rewrite rule will be written in the. htaccess file. To enable apache to normally read the content of the. htaccess file, you must configure the directory where. htaccess is located. For security, the AllowOverride attribute of the root directory is generally configured to not allow any Override, that is

Copy codeThe Code is as follows: <Directory/>
AllowOverride None
</Directory>

When AllowOverride is set to None, the. htaccess file is completely ignored. When this command is set to All, All commands with ". htaccess" scope can appear in the. htaccess file.

For URL rewrite, at least the directory must be set

Copy codeThe Code is as follows: <Directory/myblogroot/>
AllowOverride FileInfo
</Directory>

2. Enable Options FollowSymLinks and AllowOverride All in the directory that supports url rewirte

Copy codeThe Code is as follows: Alias/php "c:/web/php /"
<Directory "c:/web/php/">
Options Indexes FollowSymLinks
AllowOverride All
Order allow, deny
Allow from all
</Directory>

By using http: // localhost: 8080/php/, the/php/and its subdirectories support url rewrite.
