Detailed Explanation of the Code Snippet

Enabling Apache Options

The first section enables Apache options such as memory limits and compression:

<IfModule mod_php7.c>
    php_value memory_limit 756M
    php_value max_execution_time 18000
    php_flag zlib.output_compression on
</IfModule>
  • memory_limit: Increases PHP memory limit to handle large operations.
  • max_execution_time: Extends execution time to avoid timeout issues during heavy tasks.
  • zlib.output_compression: Enables output compression to reduce the size of transmitted data.

Enabling Mod_Rewrite

The mod_rewrite module is crucial for URL rewriting and redirection:

<IfModule mod_rewrite.c>
    RewriteEngine on

    ## Redirect HTTP to HTTPS
    RewriteCond %{HTTPS} off
    RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    ## URL rewriting for Magento
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule .* index.php [L]
</IfModule>
  • RewriteEngine on: Enables the rewrite engine.
  • RewriteCond %{HTTPS} off: Checks if the request is not using HTTPS.
  • RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]: Redirects all HTTP requests to HTTPS.

Security Enhancements

Security headers and directives to protect your Magento 2 store:

<IfModule mod_headers.c>
    Header set X-Content-Type-Options "nosniff"
    Header set X-Frame-Options "SAMEORIGIN"
    Header set X-XSS-Protection "1; mode=block"
</IfModule>

<FilesMatch "^\.">
    Order allow,deny
    Deny from all
</FilesMatch>
<Files ~ "(\.xml|\.txt|composer\.(json|lock)|package\.xml|\.git(ignore)?|\.md|\.sh|\.sample)$">
    Order allow,deny
    Deny from all
</Files>
  • X-Content-Type-Options "nosniff": Prevents MIME type sniffing.
  • X-Frame-Options "SAMEORIGIN": Protects against clickjacking.
  • X-XSS-Protection "1; mode=block": Enables XSS filtering.

Caching and Compression

Improving performance through caching and compression:

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

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType application/javascript "access plus 1 year"
    ExpiresByType text/javascript "access plus 1 year"
    ExpiresByType application/x-shockwave-flash "access plus 1 year"
    ExpiresByType image/x-icon "access plus 1 year"
</IfModule>
  • mod_deflate.c: Enables compression for various file types.
  • mod_expires.c: Sets expiration times for different types of files to leverage browser caching.

Custom Error Pages

Custom error pages enhance user experience and SEO:

ErrorDocument 403 /errors/403.html
ErrorDocument 404 /errors/404.html
ErrorDocument 500 /errors/500.html
  • ErrorDocument 403 /errors/403.html: Custom 403 Forbidden error page.
  • ErrorDocument 404 /errors/404.html: Custom 404 Not Found error page.
  • ErrorDocument 500 /errors/500.html: Custom 500 Internal Server Error page.
