Apache AllowOverride and Options detailed

Typically, the rewrite rules are written in the. htaccess file when the URL is rewritten using the Apache rewrite module. But to enable Apache to read the contents of the. htaccess file properly, you must configure the. htaccess directory. From security considerations, the allowoverride properties of the root directory are generally configured to disallow No Override, that is,

The code is as follows	Copy Code
< Directory/> AllowOverride None </directory>

When AllowOverride is set to None, the. htaccess file is completely ignored. When this directive is set to all, all directives with the ". htaccess" Scope are allowed to appear in the. htaccess file.

For URL rewrite, you need to set the directory at least

The code is as follows	Copy Code
< directory/myblogroot/> AllowOverride FileInfo </directory>

2. Enable the Options followsymlinks and allowoverride all in directories to support URL Rewirte

The code is as follows	Copy Code
alias/php "c:/web/php/" <directory "c:/web/php/" > Options Indexes FollowSymLinks AllowOverride All Order Allow,deny Allow from all </Directory>

When this is accessed through http://localhost:8080/php/, the/php/and the subdirectories underneath it will support the URL rewrite
