是sitemap.xml只加载页面还是机器人？

Question

I want to know if sitemaps are loaded by browsers or only search engines use them for crawling. I have dynamic page with multiple sections with dynamic content and generating this add extra mysql query.

Answer 1

Sitemaps can be loaded by a browser, if a visitor opens their url, but they are intended for crawlers, and browsers won't go looking for them.

I don't understand how that would relate to MySQL.
