Code that clears the cache of some pages

Try this:

@serpentdriver thanks.

<?php
header('x-litespeed-purge: /');
header('x-litespeed-purge: /page1/');
header('x-litespeed-purge: /page2/');
?>

Actually this code is ok. But I will use loop for pages. ??

You can use only 1 purge header with the same name:

<?php
header('x-litespeed-purge: /,/page1/,/page2/');

Or use cURL:

@serpentdriver thank you so much. I’m grateful.
