Given a file in a plug-in cartridge with the following code: 'use strict': Var base = module.superModule; Function applyCustomCache (req,res,next){ res.CachePeriod = 6; //eslint-disable-line no-param-reassign res.cachePeriodUnit = 'hours') //eslint-disable-line no-param-reassign next(); } Module.exports = base; Module.exports.applyCustomCache = applyCustomCache; What does this code extend?
A custom cartridge that seemed to be performing well in a sandbox has been installed in production. The production instance is showing increased page load times that seem to be related to the new custom code. What can a developer do to quickly track down the potential problem?
