How Do I Add a Cache Control Header in WordPress?

Adding a cache control header in WordPress is quite simple. Here is how you can do it:

1. In the WordPress admin area, go to Settings > Media > Cache.

2. Under the “Cache Control” heading, enter the appropriate cache control header information.

3. Click the “Update” button to save your changes.

Now, when WordPress requests a page from the internet, it will check to see if the page has already been stored in the WordPress database. If it has, WordPress will use the cached version instead of requesting the page from the internet.

Cache control headers allow you to specify which pages should be cached, how long the cache should be kept for, and whether or not the cache should be shared between sites.
