FlyingPress automatically preloads a list of URLs to ensure important pages are cached and load instantly for visitors. By default, it includes:
Home page
Posts
Pages
Custom post types
Author pages
Categories, tags, and other taxonomies
You can customize this list using the flying_press_preload_urls filter.
Where to add this code
Add the code in one of the following:
Your theme’s
functions.phpfileA custom plugin
A plugin like Code Snippets
Important
The flying_press_preload_urls filter is called multiple times, each time with a batch of URLs. Do not assume it receives the full list in a single call.
Add URLs to the preload list
add_filter('flying_press_preload_urls', function ($urls) {
$urls[] = 'https://example.com/your-page/';
$urls[] = 'https://example.com/another-page/';
return $urls;
});This will ensure your custom URLs are included during the preload process.
Remove URLs from the preload list
add_filter('flying_press_preload_urls', function ($urls) {
$remove_urls = [
'https://example.com/remove-this-page/',
'https://example.com/also-remove-this-page/',
];
$filtered_urls = array_diff($urls, $remove_urls);
return array_values($filtered_urls);
});This removes specific pages from the preload queue.
Notes
Matching is by exact URL, including protocol (http/https) and trailing slashes
Since the filter is called in batches, your logic should work for partial lists
You can both add and remove URLs in the same filter if needed
