It’s astonishing to think that nearly 43% of the web is powered by WordPress. The beauty of WordPress lies not just in its user-friendly interface but also in its intricate backend processes. One such essential backend component is the .htaccess
file—a cornerstone for any WordPress site that desires agility, security, and customization.
Did you know? More than 500 websites are built daily using WordPress, while only 60-80 per day are built on platforms like Shopify or Squarespace.
The .htaccess
(short for “Hypertext Access”) do Apache-based servers use a configuration file? In simple terms, it’s the gatekeeper of your WordPress site, allowing or denying access based on specific criteria.
But it’s not just about access. This nifty file also governs redirects, secures directories, optimizes performance, and more. It acts, in many ways, like the conductor of an orchestra, guiding different instruments (or in this case, website elements) to function harmoniously.
The .htaccess
file, a brainchild of the Apache HTTP Server Project, has been around for a while. Its roots trace back to the early days of the web when website management was mostly a matter of nerds and coders. Over time, as platforms like WordPress democratized web development, the .htaccess
file became indispensable.
So, why should Joe and Jane Blogger care about the .htaccess
file?
When you first peek into a .htaccess
file, it might seem like you’ve opened Pandora’s box of code. But fear not! We’re here to de-mystify it.
The .htaccess
file’s syntax is distinct but straightforward. Each directive—basically a command or instruction—is on a new line. Think of these as the rules governing how your website interacts with its visitors.
For example, if you wished to restrict access to a directory, you’d add a directive to your .htaccess
file specifically for that purpose.
Let’s take a quick detour to understand some frequent directives you might encounter:
Directive | Description |
---|---|
Deny from all | Prohibits all users from accessing the directory. |
Allow from [IP address] | Grants access to users from a specific IP address. |
Redirect | Helps in navigating the user from one URL to another. |
RewriteRule | Used for URL rewriting, particularly useful for SEO purposes. |
It’s essential to know that while directives are mighty tools, they’re also double-edged swords. A misplaced command can lead to website errors. Always tread carefully.
The .htaccess
file is a hidden system file used primarily on Apache servers to manage the way browsers interact with your website. WordPress uses this file to manage permalinks and can also be used for various other configurations like redirects, security enhancements, and more.
Here’s how you can locate the .htaccess
file in a WordPress setup:
public_html
directory, but this can vary if you have installed WordPress in a sub-directory..htaccess
file is a dotfile (which means it’s hidden by default). There should be an option in the File Manager settings or on the main screen to “Show Hidden Files (dotfiles)”. Make sure this option is enabled..htaccess
: You should now see the .htaccess
file in the list of files.public_html
..htaccess
: Once the hidden files are visible, you should be able to see the .htaccess
file.There are plugins available that allow you to edit the .htaccess
file directly from the WordPress admin dashboard. A popular option is “WP Htaccess Editor”.
.htaccess
: After activation, go to Settings > WP Htaccess Editor. You can view and edit the .htaccess
file here.Important Notes:
.htaccess
file before making any changes. A small error in this file can make your website inaccessible..htaccess
file, it might not exist (especially if you haven’t changed the permalink settings in WordPress). In such a case, you can create one manually using the File Manager in cPanel or an FTP client..htaccess
file. Nginx uses a different configuration system. Always check the server type before diving into .htaccess
configurations.When you set up WordPress and choose a permalink structure other than the default plain setting, WordPress will generate a .htaccess
file. This file plays an essential role in how WordPress handles permalinks.
Here’s what the default .htaccess
file typically looks like for a standard WordPress installation:
# BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress
Let’s briefly decipher what each line does:
# BEGIN WordPress
and # END WordPress
: These comments are markers indicating the beginning and the end of the WordPress-generated rules. It’s essential to keep these in place if you add custom rules to your .htaccess
file so that WordPress knows where its section begins and ends.<IfModule mod_rewrite.c>
: This checks if the mod_rewrite module is available on your server. This module is necessary for WordPress to handle its permalink structure.RewriteEngine On
: This line enables the rewrite engine, which allows WordPress to handle its custom permalink structures.RewriteBase /
: This sets the base URL for the rewrite rule and is set to the root directory by default.RewriteRule ^index\.php$ - [L]
: This rule ensures that if the request is specifically for index.php
, it is left unchanged.RewriteCond %{REQUEST_FILENAME} !-f
and RewriteCond %{REQUEST_FILENAME} !-d
: These conditions check if the requested URL corresponds to an existing file (!-f
) or directory (!-d
). If the requested URL is neither a file nor a directory, then the rewrite rule that follows is applied.RewriteRule . /index.php [L]
: This is the rule that makes WordPress permalinks function. It tells the server that if the requested URL doesn’t correspond to an existing file or directory (as determined by the conditions above), then the request should be sent to index.php
. WordPress then decides what content to serve based on the request.Remember, the above is the standard .htaccess
configuration for a default WordPress installation in the root directory. If you’ve installed WordPress in a subdirectory or have custom configurations or plugins that modify the .htaccess
, the content might differ. Always backup the .htaccess
file before making changes, as incorrect configurations can make your site inaccessible.
Venturing into the realm of .htaccess
creation? Brace yourself; it’s not as daunting as you might think.
Before diving in, make sure you’re equipped with:
Remember: With great power comes great responsibility. Creating or editing the .htaccess
file can impact your site’s functionality. Always tread with caution.
public_html
or www
..htaccess

. (Yes, it starts with a dot!)Pro-tip: Sometimes, the .htaccess
file might be hidden, especially in FTP clients. Ensure you’ve enabled viewing hidden files to find it.
Whether you’re looking to optimize your site’s performance or ramp up its security, editing the .htaccess
file is pivotal. It’s akin to fine-tuning an instrument, ensuring that it hits the right notes.
Before you can edit, you’ve got to get your hands on the file. Let’s go through the routes:
.htaccess
file..htaccess
file..htaccess
file directly from the dashboard. Handy, right?Armed with your directives, you’re set to customize:
#
symbol allows you to add comments. This can be crucial for reminding you (or informing others) about the purpose of specific directives.Example:
# Redirect old URL to new URL Redirect 301 /oldpage.html http://www.yoursite.com/newpage.html
.htaccess
file.Remember the golden rule: Always test changes in a staging environment before implementing them on your live site. This ensures your users remain blissfully unaware of any backstage tweaks you’re making.
Now that we’re familiar with the how-to, let’s dive into the why.
A 301 redirect indicates that a page has been permanently moved to a new location. It’s the most common redirect used for SEO purposes.
Syntax:
Redirect 301 /old-page.html /new-page.html
This will redirect http://yourdomain.com/old-page.html
to http://yourdomain.com/new-page.html
.
If you’re moving your website to a new domain, you can use a 301 redirect for the entire domain.
Syntax:
RewriteEngine On RewriteCond %{HTTP_HOST} ^olddomain.com [OR] RewriteCond %{HTTP_HOST} ^www.olddomain.com RewriteRule (.*) http://newdomain.com/$1 [R=301,L]
Replace olddomain.com
with your old domain name and newdomain.com
with your new domain name.
You may want to choose a preferred domain, either with www
or without.
To force “www”:
RewriteEngine On RewriteCond %{HTTP_HOST} ^yourdomain.com [NC] RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [L,R=301]
To force non-“www”:
RewriteEngine On RewriteCond %{HTTP_HOST} ^www.yourdomain.com [NC] RewriteRule ^(.*)$ http://yourdomain.com/$1 [L,R=301]
Replace yourdomain.com
with your actual domain name.
Syntax:
RedirectMatch 301 ^/old-directory/ http://yourdomain.com/new-directory/
This will redirect all files and sub-directories from old-directory
to new-directory
.
For instance, if you want to redirect all .jpg
images from one directory to another.
Syntax:
RedirectMatch 301 /old-directory/(.*\.jpg) /new-directory/$1
There might be instances where you’d like to set up a temporary redirect. This can be done using a 302 redirect.
Syntax:
Redirect 302 /temporary-old-page.html /temporary-new-page.html
Important Notes:
.htaccess
file.The .htaccess
file is a powerful configuration file used by Apache-based web servers. It offers an array of functionalities, including enhancing security for WordPress sites. Here are several .htaccess
security tips you can implement to protect your WordPress site:
To ensure no one can view or modify the .htaccess
file:
<Files .htaccess> Order Allow,Deny Deny from all </Files>
To prevent users from viewing the contents of your directories:
Options -Indexes
This prevents the server from displaying its version information, potentially hiding version-specific vulnerabilities:
ServerSignature Off
While not directly done via .htaccess
, limiting login attempts can thwart brute-force attacks. Plugins like “Limit Login Attempts Reloaded” can help.
The wp-config.php
file contains sensitive data. To protect it:
<Files wp-config.php> Order Allow,Deny Deny from all </Files>
Some known bad bots can be blocked by user agents. This is just a general example; adjust according to the threats you face:
RewriteCond %{HTTP_USER_AGENT} ^.*(agent1|Wget|Catall Spider).*$ [NC] RewriteRule .* - [F,L]
To safeguard core WordPress includes files:
<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^wp-admin/includes/ - [F,L] RewriteRule !^wp-includes/ - [S=3] RewriteRule ^wp-includes/[^/]+\.php$ - [F,L] RewriteRule ^wp-includes/js/tinymce/langs/.+\.php - [F,L] RewriteRule ^wp-includes/theme-compat/ - [F,L] </IfModule>
If you don’t need XML-RPC functionality and want to block it for security reasons:
<Files xmlrpc.php> Order Allow,Deny Deny from all </Files>
This helps prevent attackers from scanning your website for vulnerabilities:
<IfModule mod_evasive20.c> DOSHashTableSize 3097 DOSPageCount 2 DOSSiteCount 50 DOSPageInterval 1 DOSSiteInterval 2 DOSBlockingPeriod 10 DOSLogDir "/var/log/httpd/evasive" </IfModule>
Ensure file permissions are set correctly (not directly an .htaccess
tip, but crucial for security):
wp-config.php
: 600Note: Always backup your .htaccess
file before making changes. A single typo can result in a non-functioning website. Additionally, not all hosting environments support all directives, so testing changes in a staging environment, when possible, is best practice. Always stay updated on security best practices as the landscape continually evolves.
Forcing HTTPS is a critical security measure for websites. When you force HTTPS, you ensure that all data between your server and your users is encrypted, making it harder for eavesdroppers to snoop on the data being transferred.
If your website is on an Apache server, you can use the .htaccess
file to force HTTPS (SSL) for all visitors. Here’s how:
RewriteEngine On RewriteCond %{HTTPS} !=on RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This code does the following:
RewriteEngine On
activates the rewrite module.RewriteCond %{HTTPS} !=on
checks if HTTPS is not active for the current connection.RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
redirects all non-HTTPS traffic to HTTPS..htaccess
file back to your server if you accessed it via FTP.http://
prefix. It should automatically redirect you to the https://
version. Make sure to clear your browser cache or use a private/incognito window to ensure you’re seeing the most recent changes.Potential Issues & Solutions:
//example.com/resource.jpg
without the http:
or https:
)..htaccess
file or some server configurations. In such cases, revert to your backup and consult with your hosting provider or a web developer.Remember, forcing HTTPS is a step towards a more secure web, and it also has SEO benefits, as search engines give preference to encrypted websites.
Utilizing the .htaccess
file to enhance your WordPress site’s performance is a great strategy, especially when combined with other performance optimization techniques. Here are some .htaccess
rules that can boost performance:
GZIP compression reduces the size of your site’s files, speeding up load times:
<IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript </IfModule>
Leverage browser caching by setting expiration dates for certain file types:
<IfModule mod_expires.c> ExpiresActive On ExpiresByType image/jpg "access 1 year" ExpiresByType image/jpeg "access 1 year" ExpiresByType image/gif "access 1 year" ExpiresByType image/png "access 1 year" ExpiresByType text/css "access 1 month" ExpiresByType application/pdf "access 1 month" ExpiresByType application/javascript "access 1 month" ExpiresByType application/x-javascript "access 1 month" ExpiresByType application/x-shockwave-flash "access 1 month" ExpiresByType image/x-icon "access 1 year" ExpiresDefault "access 2 days" </IfModule>
ETags can cause issues with site speed when used in a clustered server environment:
FileETag None
Keep-Alives allow the server and browser to establish a connection for multiple files, reducing latency:
<IfModule mod_headers.c> Header set Connection keep-alive </IfModule>
Prevent others from linking to your images directly, saving bandwidth:
RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC] RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?google.com [NC] RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F,L]
Replace yourdomain.com
with your actual domain name.
A Content Security Policy can speed up your site and make it more secure by reducing the risk of cross-site scripting attacks:
<IfModule mod_headers.c> Header set Content-Security-Policy "default-src 'self'; font-src 'self' https://fonts.googleapis.com; img-src 'self' https://www.google-analytics.com; script-src 'self' https://www.google-analytics.com; style-src 'self' https://fonts.googleapis.com;" </IfModule>
This is a basic CSP setup; you might need to adjust it based on the external resources you use.
Final Note: Always remember to back up your current .htaccess
file before making any changes. Additionally, performance improvement isn’t just about adding rules to the .htaccess
file. Use performance plugins, optimize images, utilize CDNs, and perform regular site maintenance to ensure your WordPress site remains fast and efficient.
When running a WordPress Multisite (WPMU) installation, the .htaccess
file rules will differ from a standard WordPress installation. The .htaccess
file is critical in ensuring that your network of sites runs smoothly.
Let’s explore the standard .htaccess
configurations for WordPress Multisite setups:
If your Multisite setup uses subdomains (e.g., site1.example.com, site2.example.com), the .htaccess
file should look like:
RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] # add a trailing slash to /wp-admin RewriteRule ^wp-admin$ wp-admin/ [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] RewriteRule ^(wp-(content|admin|includes).*) $1 [L] RewriteRule ^(.*\.php)$ $1 [L] RewriteRule . index.php [L]
If your Multisite setup uses subdirectories (e.g., example.com/site1, example.com/site2), the .htaccess
file will be:
RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] # add a trailing slash to /wp-admin RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L] RewriteRule . index.php [L]
Key Notes:
RewriteRule
directives essentially allow WordPress to handle requests and direct them to the appropriate site within your Multisite network..htaccess
file before making changes. This ensures you can quickly restore the original configuration if anything goes wrong..htaccess
rules based on the server environment detected and the type of network chosen (subdomains vs. subdirectories). It’s always a good idea to use the rules provided during the setup process unless you have a specific need to customize them further.Finally, always monitor your Multisite network after changing .htaccess
rules to ensure all sites operate correctly and efficiently. If you’re unfamiliar with these rules or if any aspect of the setup seems overwhelming, consider seeking expert help or consulting with your hosting provider for guidance.
When maneuvering through the intricate terrains of the .htaccess
file, occasional hiccups are inevitable. But, like any experienced traveler, knowing the pitfalls can make the journey smoother.
This error often rears its head when there’s a syntax error in your .htaccess

directives to ensure they’re in line with current best practices.As you become more comfortable with the .htaccess
file, you’ll uncover a realm of advanced capabilities that can further refine your website’s functionality.
Instead of showing the generic server error messages, you can redirect users to custom error pages, offering a better user experience.
# Custom error pages ErrorDocument 404 /custom-404.html ErrorDocument 500 /custom-500.html
Ensure that you’ve created the custom pages (custom-404.html
, custom-500.html
) within your root directory.
If you’ve noticed suspicious activity or excessive crawling from specific bots, you can block them.
# Block user agents SetEnvIfNoCase User-Agent "bad_bot" bad_bot Deny from env=bad_bot
Replace bad_bot
with the user agent you intend to block.
For sites with SSL (and you should definitely have SSL!), force users to access your site via HTTPS.
# Force HTTPS RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
To avoid duplicate content issues with search engines, choose either the ‘www’ version or the non-‘www’ version of your domain as the primary.
# Force www RewriteEngine On RewriteCond %{HTTP_HOST} ^yoursite\.com [NC] RewriteRule ^(.*)$ http://www.yoursite.com/$1 [L,R=301]
OR
# Remove www RewriteEngine On RewriteCond %{HTTP_HOST} ^www\.yoursite\.com [NC] RewriteRule ^(.*)$ http://yoursite.com/$1 [L,R=301]
Remember to replace yoursite.com
with your actual domain name.
Stop other websites from using your images without your permission.
# Prevent image hotlinking RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yoursite.com [NC] RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F,L]
Again, replace yoursite.com
with your actual domain.
