After creating a cascade drop-down list box with JQuery, the user can choose a state from the first drop-down and then the second drop-down will be filled with the relevant cities based on the selected state. However, I am facing an issue with caching in the second drop-down. If the user clicks the back button and then forwards again, the city drop-down contents are empty. Is there a method to instruct the browser to cache the data?
Since we are dealing with HTTP, you'll need to make sure to configure the caching and last modified headers when sending the AJAX request. Additionally, it would be beneficial to include it in the DOM during the request so that it is accessible for the second drop-down menu.
