CDN Caching Control in SuiteScript Server Scripts

CDN caching plays a critical role in enhancing performance by temporarily storing resources closer to the user, thereby reducing load times. In SuiteScript, developers can leverage CDN caching to specify how long resources should be cached, ensuring that the latest versions are available when needed. This capability is particularly useful in scenarios where data freshness needs to be balanced with performance requirements.

Method Description

The method sets the CDN caching duration for a given resource. This means developers can instruct how long the content should be stored before it is considered stale and needs to be fetched again from the server.

Returns

This method returns void, indicating it does not return any value upon execution.

Supported Script Types

• Server scripts: This method is exclusively available for use in server-side scripts.

Governance

This method does not require specific governance limits, making it straightforward to implement without performance concerns over quota limits.

Module

The method is part of the N/http Module used for handling HTTP requests and responses in SuiteScript.

Parent Object

It operates as a member of the http.ServerResponse object, which encapsulates the response object for server-side HTTP requests.

Parameters

The method expects the following parameters encapsulated in a JavaScript object:

Error Handling

It is important to handle errors when using this method. The following error code may be thrown:

• Error Code: SSS_MISSING_REQD_ARGUMENT
  • Message: Missing a required argument: {param name}
  • Thrown If: The options.type parameter is not specified.

Example Syntax

Below is an example of how to use this method within a server script, demonstrating its syntax:

// Set CDN cache duration for an HTTP response
serverResponse.setCdnCacheable({
    type: http.CacheDuration.MAX
});

This example showcases setting the caching duration to the maximum value, ensuring optimal loading performance before the cache expires.
