The definitive guide to htaccess and WordPress

What are htaccess files?

Htaccess files are configuration files used in Apache web server. They are used to override the main web server configuration for a particular directory. For .htaccess files to work, the main Apache web server configuration option AllowOverride must be enabled. If the AllowOverride option is not switched on, then the .htaccess file configurations will not work and the main web server configuration will be applied. So before applying any configuration changes using .htaccess files, always check that the AllowOverride option is enabled.

WPWhiteSecurity Webmaster TIP: .htaccess file are very powerful and the slightest syntax error, such as forgetting a ‘<’ character, might break the functionality of your website. Therefore before making any changes to an existing .htaccess file always make a backup first. Once you apply the changes test your website thoroughly.

Performance Issues

When .htaccess files are used, each time someone visits your website the Apache web server must search through each and every directory within the domain and load all .htaccess files configurations. Such operation will not affect the performance of low traffic website, though the web master might notice performance degradation in high traffic websites. Therefore .htaccess files should only be used when the main web server configuration is not accessible, as in a web hosting environment. If the Apache web server configuration is accessible, all the configuration directives should be specified at server level.

Htaccess files for WordPress

Htaccess files are very common with WordPress users since they can be used to improve both the performance and also the security of a WordPress blog or website. Below is a list of WordPress tutorials on how you can use .htaccess files for securing and boosting the performance of your WordPress.

Modifying the WordPress htaccess file

When you enable Permalinks in WordPress an .htaccess file is created in the root directory of your WordPress installation. When WordPress writes to an .htaccess file it always writes the data between the BEGIN WordPress and END WordPress .htaccess file comments. As seen in the example below, these two lines start with a hash ‘#’ character, which means such lines are comments and will not affect the configuration.

# BEGIN WordPress
# END WordPress

When updating the default WordPress .htaccess file it is important to NEVER add any configuration directives between those two comment lines. Any configuration directives between these two comments might be overwritten by WordPress.
