Chrome“始终保持这些网站处于活动状态”URL例外语法及设置生效验证等相关技术问题咨询

Hey there! Let's tackle your questions about Chrome's tab retention settings one by one— I know it's so frustrating when your important tabs get unloaded out of nowhere.

URL例外规则的语法说明 #

First off, Chrome uses glob patterns (not regular expressions) for these exceptions, which is way simpler once you get the hang of it:

• You don't need to include https:// or http:// prefixes— Chrome automatically matches all protocols for the domain/path you enter.
• Use the * wildcard to match any sequence of characters (including slashes), and ? for single characters.
• Quick examples to make this concrete:
  • Keep all Gmail tabs active: mail.google.com (this works for all Gmail pages) or *mail.google.com* (if you want to cover any subpaths)
  • Lock down a specific Google Sheet: docs.google.com/spreadsheets/d/abc123xyz
  • Cover every page under a domain: *.example.com (matches all subdomains of example.com)

验证设置是否生效：chrome://discards/ 检查 #

Great question about chrome://discards/— yes, your exceptions should absolutely show up here! If your Gmail tab still says "Auto Discardable: Yes" after adding the rule, here's what might be going on:

• Double-check your exception format: Maybe you added extra characters (like a trailing slash or full URL with https://) that's throwing it off. Stick to just the domain or path as we covered.
• Restart Chrome: Sometimes new rules don't kick in until you close and reopen the browser.
• Rule out extension interference: Try testing in Incognito mode (where extensions are disabled) to see if the status changes— some extensions can mess with Chrome's tab management settings.

相关问题汇总解答 #

You had a few related questions, so let's wrap those up too:

• How do I stop Chrome from killing my background tabs?
  Beyond adding URL exceptions, you can:
  • Pin your most critical tabs— pinned tabs have higher priority and won't be discarded unless your system is extremely low on memory.
  • Disable automatic tab discarding entirely via chrome://flags/#automatic-tab-discarding (note: Chrome flags are experimental and might change or be removed in future versions).
• Stop Chrome from unloading pinned tabs?
  Pinned tabs are already protected by default, but combining them with URL exceptions adds an extra layer. If they're still getting unloaded, your system is probably running out of RAM— try closing unused apps or tabs to free up memory.
• How to force Chrome to keep tabs in memory?
  The most reliable method is setting up correct URL exceptions in the "Always keep these sites active" list. Make sure your rules are specific enough (but not overcomplicated) to cover the pages you care about. Avoid opening more tabs than your system can handle— Chrome's auto-discard is a memory-saving measure at its core.
• Can I keep a Chrome tab always active for a specific site?
  Yep! Just add that site's domain (or a specific path if you only want certain pages) to the exception list. Chrome will automatically recognize when you're on that site and prevent the tab from being discarded.
