Managing Cache in the Caching Tab

The Caching Tab in Nubius CloudShield allows you to control how Cloudflare caches your website’s content, improving performance and reducing load on your origin server.

To access these settings:

1. Log in to the Nubius Customer Portal.

2. Navigate to Services → My Services.

3. Select your Nubius CloudShield service.

4. Click Manage Cloudflare for the domain you want to configure.

5. Go to the Caching Tab.
   

Caching Options

1. Caching Level

Determines how Cloudflare caches your website’s content:

• No Query String – Only caches files without a query string (example.com/image.jpg).

• Ignore Query String – Serves the same cached resource even if query strings are different (example.com/image.jpg?v=1 and example.com/image.jpg?v=2 will load the same cache).

• Standard (Default) – Caches static content while dynamic content is served directly from the origin.

• Aggressive – Caches everything, including query string variations.

Recommended: Use Standard for most websites.

2. Browser Cache Expiration

Defines how long a visitor’s browser keeps cached files before requesting a fresh copy from Cloudflare.

• Options range from 30 minutes to 1 year.

• Shorter durations (e.g., 30 minutes – 1 hour) are best for frequently updated sites.

• Longer durations (e.g., 1 month – 1 year) improve performance for static sites.

3. Purge Cache (Individual Files)

• Allows you to remove specific files from Cloudflare’s cache without clearing everything.

• Useful when updating assets like images, CSS, or JavaScript files.

• To purge a file:

  1. Enter the file URL (e.g., https://example.com/style.css).

  2. Click Purge File.

4. Purge Cache (All Files)

• Clears all cached files stored by Cloudflare.

• Use only when making major website updates.

• Note: This can temporarily slow down your website until Cloudflare rebuilds the cache.

5. Always Online

• Keeps your website accessible even if your origin server goes down.

• Cloudflare serves a cached version of your website until your server is restored.

• Recommended for high-availability sites.

6. Development Mode

• Disables caching temporarily to allow developers to see live changes.

• Expires after 3 hours automatically.

• Enable when making design changes, updating CSS/JS, or testing new features.

Best Practices for Caching

• Set Caching Level to Standard for optimal performance.

• Adjust Browser Cache Expiration based on how frequently your content updates.

• Use Purge Cache (Individual Files) instead of clearing everything when making small updates.

• Keep Always Online enabled for reliability.

• Enable Development Mode when making real-time changes to your site.
