Error Handling in SuiteScript Server-Side CDN Cache Management

CDN caching management is crucial for optimizing web performance and ensuring efficient resource delivery. This article discusses error handling when setting CDN caching in SuiteScript, specifically within server-side scripts.

What is the Method for Setting CDN Caching?

The method setCdnCacheable allows developers to control CDN caching duration, significantly affecting how responses are handled. This method returns no output (void) and is specifically designed for server scripts.

Supported Script Types

• Server Scripts: The setCdnCacheable method can only be utilized in server scripts. For more detailed information on the different types of SuiteScript, check the SuiteScript 2.x Script Types documentation.

Governance

This method does not impose governance limits, which means you can set CDN cacheable options without restrictions on execution times or limits.

Parameters for setCdnCacheable

The method accepts an options parameter that is a JavaScript object containing essential types:

Note: When invoked through a Suitelet, setting options.type to UNIQUE ensures that the Suitelet is executed every time its URL is requested, preventing any caching from occurring.

Common Errors

During implementation, you may encounter the following error:

Syntax Example

Here's a basic syntax example that demonstrates how to set the CDN cacheable settings for a server response. Note that this is non-functional as presented, but illustrates proper usage:

1// Additional code can be placed here
2...
3serverResponse.setCdnCacheable({
4    type: http.CacheDuration.MAX
5});
6...
7// Remaining code can continue here

Conclusion

Incorporating proper error handling and understanding the CDN caching methods enhances the efficiency of SuiteScript server responses. By adhering to best practices, you can ensure your application provides the best performance possible.
