The .htaccess file allows you to override some settings of the web server which will allow you to control the way your web site responds to visitors. We support a number of directives and configurations which you may use to change the behavior of your web site. Below are some examples.
Error Documents
Please refer to the following
document which will describe in detail how to use a .htaccess file to enable error document handling.
Rewrite Engine (mod_rewrite)
The rewrite engine, or mod_rewrite allows you to alter the URL displayed in the address bar while redirecting the visitor to a different page of your choice. While it is a very powerful feature and can accomplish a lot of tricks, it is usually used to create search engine friendly URLs.
Example 1: mod_rewrite
Address bar shows: http://yourdomain.com/tutorials/3/0.php
Actual web page served: http://yourdomain.com/tutorials.php?req=tutorial&id=3&page=0
2 | RewriteRule ^tutorials/(.*)/(.*).php /tutorials.php?req=tutorial&tut_id=$1&page=$2 |
Example 2: mod_rewrite
Address bar shows: http://yourdomain.com/directory/xyz.html
Actual web page served: http://yourdomain.com/directory/index.php?p=xyz
3 | RewriteRule ^([a-z]+).html$ /index.php?p=$1 [R,L] |
Example 3: Force index.php to handle all requests
For dynamic applications which use a single file to control the web site, it is often desirable to force all URLs to be passed to a single script or file. This will allow you to create very flexible search engine friendly URLs and let your application’s code decide which page to display. This code example comes from Wordpress and shows how every URL is passed to index.php which then determines which page to display.
3 | RewriteCond %{REQUEST_FILENAME} !-f |
4 | RewriteCond %{REQUEST_FILENAME} !-d |
5 | RewriteRule . /index.php [L] |
