Chrome清理DNS缓存是否删除历史等数据？能否单独更新单站DNS记录？

Hey there, let's tackle your two Chrome DNS-related questions clearly:

1. 执行Chrome DNS缓存清理时，会删除历史记录、自动填充或密码吗？ #

Absolutely not. Chrome's DNS cache is a separate storage layer that only stores recent domain-to-IP address mappings. It has no overlap with your browsing history, autofill data, or saved passwords—those are all stored in entirely different parts of the browser.

When you run a DNS cache clear (via chrome://net-internals/#dns > "Clear host cache"), you're only wiping those IP mapping records. All your personal user data stays completely intact.

2. 能否仅针对个人作品集网站更新Chrome的DNS记录，而非全局清理？ #

Chrome doesn't have a built-in "single site DNS refresh" button, but there are two straightforward workarounds to achieve exactly what you want:

• Remove the specific domain from DNS cache: Open chrome://net-internals/#dns, look for your portfolio website's domain in the "Hosts" list, and click the "Remove" button next to it. Once removed, reloading your site will force Chrome to fetch the latest DNS records (and thus recognize your new SSL certificate).
• Force a hard page reload: On Windows/Linux, press Ctrl + Shift + R; on Mac, press Cmd + Shift + R. This bypasses all local cache (including DNS) and reloads the site from scratch, pulling the most up-to-date DNS info automatically.
