How can Joomla caching affect the effectiveness of combining requests in a PHP website and what steps can be taken to address this issue?
Joomla caching can affect the effectiveness of combining requests in a PHP website by caching the individual requests separately, leading to redundant requests being made. To address this issue, you can disable Joomla caching for the specific requests that you want to combine.
// Disable Joomla caching for specific requests
$cache = JFactory::getCache('com_content', '');
$cache->setCaching(0);
