.00 Solid Base .htaccess.md

Solid Base .htaccess

Creating a solid base for your .htaccess file. Currently includes RewriteBase, Security (against indexes, files, etc.), and Expires Headers (caching, performance).

• The URL REWRITES would go at the top of the file.
• The SECURITY and the WEB PERFORMANCE can go towards the bottom... before and WordPress or WP Super Cache items.
• UPDATE 2013-08-21: Added code for forcing either non-www or www. on URLs. Also added the MultiViews option.
• UPDATE 2013-08-23: Added specific code for wp-config.php
• UPDATE 2013-10-04: Increased favicon expire time.
• UPDATE 2014-02-05: Removed the Force URL rewrites since there's more than one option.
• UPDATE 2014-12-10: Updated Expires Headers
• UPDATE 2015-04-10: Updated file security
