.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

If you need to force index.XXX or home.XXX to rewrite to the root of whatever folder...

# Force index.XXX to rewrite to the root of whatever folder. SRC: http://kevinthompson.info/blog/2011/03/04/completely-remove-index-php-from-expressionengine-urls.html
RewriteCond %{THE_REQUEST} ^GET.*(index|home)(\d)?(\.php|\.html?) [NC]
RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,L]

Improved force trailing slash code (if you need to force a trailing slash on the end of your URLs to avoid duplicate content issues)...

#2014-02-28 Eric R.: trailing slash fix SRC: http://stackoverflow.com/a/1668741/284091
# checks for filenames
RewriteCond %{REQUEST_FILENAME} !-f
# skips any URLs with a . the end indicating a file extension
RewriteCond %{REQUEST_URI} !\.[^.]+$
# adds trailing slash, but checks to see if there's already a slash present
RewriteRule ^(.*(?:[^\/]))$ $1/ [L,R=301]

You can add this towards the top of the .htaccess (just after the force www. code would be ideal).

I'm using this to remove .html and .php file extensions and 301 to the same slug on sites that have been ported from static to Genesis Wordpress.

# Remove file extension from URL if porting a static site to Genesis Wordpress
RewriteCond %{REQUEST_URI} !^/wp-.+$
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.(html|php) [NC]
RewriteRule ^ %1/ [R=301,L,NC]

I added some more security code, so be sure to CHANGETHENAMEOFYOURWEBSITEHERE.com where it exists above.
