In CodeIgniter, how is a controller differentiated when handling AJAX requests as opposed to standard requests?
- AJAX requests must be routed to a different controller
- AJAX requests must have a specific parameter in the URL
- Controllers check the 'X-Requested-With' header for 'XMLHttpRequest'
- Controllers do not differentiate between AJAX and standard requests
In CodeIgniter, controllers can differentiate between AJAX and standard requests by checking the 'X-Requested-With' header. If the header is set to 'XMLHttpRequest,' it indicates an AJAX request. This allows controllers to customize their response based on the type of request being made.
