Common .htaccess Configurations

Redirecting HTTP to HTTPS

Forcing HTTPS ensures all traffic is encrypted:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

Creating 301 Redirects (Permanent Redirect)

Redirect an old URL to a new one:

Redirect 301 /old-page.html https://yourwebsite.com/new-page.html

Blocking Specific IP Addresses

To block unwanted visitors from accessing your site:

Order Deny,Allow
Deny from 123.45.67.89
Deny from 111.222.333.444

Password Protecting a Directory

To restrict access to certain directories:

1. Create an .htpasswd file:

   htpasswd -c /home/user/.htpasswd username

2. Add the following to .htaccess:

   AuthType Basic
   AuthName "Restricted Area"
   AuthUserFile /home/user/.htpasswd
   Require valid-user

Custom Error Pages

Set up a custom 404 error page:

ErrorDocument 404 /custom-404.html

Enabling Gzip Compression

Speed up website load times by compressing files:

<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/javascript
</IfModule>
