The allowoverride of Apache and the use of options

Source: Internet
Author: User
The allowoverride parameter is to indicate whether the Apache server is looking for a. htacess file as a configuration file, and if set to none, the server ignores the. htacess file, if set to all, Then all the instructions in the. htaccess file will be rewritten. For allowoverride, you can also specify the following types of instructions that can be overridden.

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,

Copy code code as follows:
<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

Copy code code as follows:
< directory/myblogroot/>
AllowOverride FileInfo
</directory>


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

Copy code code as follows:
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
