<?php

// Get the current sitemap URL from the query parameter.
$sitemapURL = $_GET['sitemap'];

// Construct the URL to fetch the sitemap from pro-sitemaps.com.
$fetchURL = "https://www.pro-sitemaps.com/" . $sitemap;

// Set the Content-Type header to indicate an XML file.
header('Content-Type: application/xml');
