Enabling data compression using the mod_deflate module

The mod_deflate module in Apache allows you to compress output before sending it to client browsers. On ruachost.com, enabling compression reduces page load times and bandwidth usage, improving overall site performance.

Why Use mod_deflate?

• Speeds up website loading by reducing file sizes.
• Saves bandwidth costs.
• Improves SEO rankings (Google favors faster sites).
• Works seamlessly with most modern browsers.

Steps to Enable Compression

Managed Hosting Accounts (cPanel)

1. Log in to cPanel.

2. Go to Software → Optimize Website.

3. Under Compress Content, choose one of the following:

   • Compress All Content – compresses everything.
   • Compress Specified MIME Types – compresses only certain file types.

4. Click Update Settings.

5. Test compression using tools like GiftOfSpeed Gzip Test.

Unmanaged Hosting Accounts

Edit your .htaccess file to enable compression.

Option 1: By File Extension

<IfModule mod_deflate.c>
  <FilesMatch "\.(js|css|html|php)$">
    SetOutputFilter DEFLATE
  </FilesMatch>
</IfModule>

Option 2: By MIME Type

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

• This compresses HTML, CSS, JavaScript, XML, and plain text files.
• To disable compression, comment out or remove the relevant lines.

Verifying Compression

1. Visit GiftOfSpeed Gzip Test.
2. Enter your domain name.
3. The tool will confirm whether compression is active.

Important Notes

• Older Apache versions used mod_gzip; mod_deflate replaces it in Apache 2+.
• Compression is already enabled on shared hosting accounts by default.
• For VPS or dedicated servers, Ruachost support can install mod_deflate if missing.
• Avoid compressing already compressed files (e.g., images, PDFs, ZIPs).
