Browser Cache Rule

Configure browser-side caching behavior for different resource types using Browser Cache Rules.

Browser Cache Rule allows you to control how long different resource types remain cached in the visitor’s browser.

This improves performance by reducing repeated network requests for static or frequently accessed files.

You can manage Browser Cache Rules in the Medianova Control Panel or via API.

Configure Browser Cache Rules

Log in to the Medianova Control Panel, select a CDN resource in the CDN section, and navigate to the Caching tab.

1

Add a Browser Cache Rule

A dialog opens for creating a new Browser Cache Rule.

The 'Add Browser Cache Rule' dialog box appears after clicking Add.

2

Select the Type for the rule.

Choose how the rule matches content:

• All Files – Applies rule to all content.

• Full Path – Applies to an exact URL path.

• Directory – Applies to all content under a directory (for example: /images/).

• File Extension – Applies to file types (for example: .jpg, .css, .js).

3

Set the Priority

Select Priority to determine the rule evaluation order.

4

Select the Cache Mode.

• Origin – Uses caching headers from the origin.

• No Cache – Disables browser caching.

• Cache – Forces caching for a defined duration.

5

Select Add to create the rule.

6

Configure HTML/JSON Application

Enable or disable Apply the HTML/JSON files to define whether rules also apply to .html and .json responses.

7

Select Submit to apply

Edit a Browser Cache Rule

Delete a Browser Cache Rule

1

Open the options menu for the rule and select Delete.

2

Confirm the deletion to remove the rule.

3

Select Submit to apply the update.

• Rules are evaluated in order of Priority, where smaller numbers indicate higher precedence.

• Browser Cache Rules control browser-side caching only, not CDN edge caching.

• The Apply the HTML/JSON files toggle affects all rules globally.

• When Cache Mode = Origin, browser caching behavior follows origin headers; No Cache forces revalidation; Cache overrides browser behavior with a fixed duration.

Best Practices

• Use file extension rules to cache static assets like .js, .css, and .png for long durations.

• Use no cache mode for frequently updated resources (e.g., .html, .json APIs).

• Assign high priority to specific full path or directory rules if they should override global rules.
