Page Rules Settings

Learn about the actions Medianova CDN can take based on a page rule, and the configuration options for each setting.

Settings control the actions Medianova CDN takes once a request matches the URL pattern defined in a page rule.

The table below outlines all settings available in Page Rules from the Medianova Panel.

Medianova can implement custom page rule configuration at your request, for example network rate limit and security headers.

Setting	Description	Packages
Cache Type	Configure edge caching behaviour and TTL	All
CORS	Configure cross-origin resource sharing headers	All
Custom Header	Add or remove request and response headers	All
Downloadable Query String Header	Trigger browser to download file	All
Exact Match	Disable recursive URL matching	All
Hotlink Protection	Configure specific hotlink protection	Starter, Growth, Enterprise
Options Request	Enable OPTIONS requests	All
Query String Caching	Configure specific query string caching	All
Range Based Caching	Disable range based caching	All

Cache Type

Use the Cache Type setting to control CDN caching.

Select Edge to specify how long the CDN may cache responses.

Select Origin to instruct the CDN to determine the maximum cache duration from origin response headers cache-control or expires .

Select Dynamic to disallow the CDN to cache responses for matching URLs.

CORS

The CORS setting controls the cross-origin resource sharing (CORS) header access-control-allow-origin in responses served by Medianova CDN edge servers.

Option	Description
On	Edge servers use the settings of the Cors Header feature
Off	Edge servers forward the CORS header from origin
Dynamic	Outgoing CDN responses have the access-control-allow-origin: <origin> CORS header, where <origin> is the value of the Origin header in the incoming request

Custom Header

Set the Custom Header Type to Default to have the CDN inherit the parent settings, as configured in the Headers tab in the Medianova Panel.

Set the Custom Header Type to Custom to disable parent setting inheritance and customize the headers. Configure the CDN to manipulate headers in requests to origin, or to manipulate headers in responses the CDN sends to clients/browsers.

Option	Description
Add Origin Request Header	Add header to requests to origin
Remove Origin Request Header	Remove header from requests to origin
Add CDN Response Header	Add header to outgoing CDN responses
Remove CDN Response Header	Remove header from outgoing CDN responses

Downloadable Query String Header

Use the Downloadable Query String Header setting to trigger browsers to download a file instead of displaying it.

In the page rule, toggle the setting on and specify a Downloadable Query String Header Key and a Downloadable Query String Header Value. For example, set the key to download and the value to yes to trigger a browser to download the file when it loads a URL with query string ?download=yes (and the URL matches on File Path and File Extension as configured in the page rule).

The CDN will send the content-disposition response header with in its value the attachment attribute and the path to the file. For example, content-disposition: attachment; filename="manual.pdf"

Exact Match

Turn on Exact Match to disable recursive directory processing. For example, if the page rule has File Path /dir/ and Exact Match is enabled, only URLs for files in that exact directory will match, while with Exact Match off (default) the page rule would also take action for files in subdirectories like /dir/subdir/ .

Hotlink Protection

If Hotlink Protection is turned on in the parent setting in the Security tab, a new page rule will inherit its status and configuration. The Update a Page Rule screen then shows the Hotlink Protection toggle in the active state and the Hotlink Protection Type is set to Default.

Change the Hotlink Protection Type to Custom to and confgure the Hotlink Protections that must apply to matching URLs.

Options Request

Turn on Options Request to have the CDN send edge-generated responses to requests with the OPTION method in case the origin does not respond to OPTION requests.

Query String Caching

While a new page rule inherits the parent setting for Query String Caching (as configured in the Caching tab in the Medianova Panel), you can customize the CDN query string caching behavior for matching URLs.

Query String Caching in Page Rules has four options:

Option	Description
Retain All	Query string is part of the cache key. /image.jpg?123 is cached separately from /image.jpg?456
Ignore All	All query string parameters are ignored. /image.jpg?123 and /image.jpg?456 are considered the same response
Retain Specific	Only the specified query string parameters are included in the cache key
Ignore Specific	The specified query string parameters are ignored when determining the cache key

Range Based Caching

Page Rules allows you to enable/disable Range Based Caching for matching URLs, regardless of the parent setting for Range Based Caching (as configured in the Caching tab in the Medianova Panel)..
