如何程序化阻止Edge显示‘您遇到了老式网页技术’提示？

Hey there! Since you're gearing up to launch that shiny new HTML5 player that works with both IE11 and Edge, let's work through how to get rid of that annoying "vintage site" warning in Edge. Here are some practical, actionable steps:

1. Strip Out Silverlight Traces & Update Site Metadata #

Edge flags sites as vintage largely based on Silverlight-related code and metadata. Start here:

• Remove all <object>/<embed> tags that reference the Silverlight plugin from your pages
• Update your page's meta tags to explicitly declare modern compatibility:

  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="supported-color-schemes" content="light dark">
  

• Make sure your new HTML5 player code loads first, fully replacing the old Silverlight initialization logic

2. Use Edge's Compatibility Submission Tools #

Microsoft has a system to update site compatibility statuses:

• Open edge://compat/vendors in Edge (this is for developers/teams managing enterprise sites) and submit your site's update details—clearly state you've removed Silverlight and upgraded to an HTML5 player
• After completing full compatibility testing, request Microsoft to remove your site from their vintage site database

3. Temporary Transition Workaround (If You're Rolling Out Gradually) #

If you're doing a phased launch, soften the blow for Edge users:

• Detect Edge browsers and show a custom message letting users know the site has been upgraded, guiding them to click the "vintage site" prompt in the address bar and select "Open without using vintage site mode"
• Alternatively, use JavaScript to detect Edge and redirect users to a dedicated entry point for your new HTML5 player (if you have one deployed separately)

4. Clean Up Server-Side Silverlight Resources #

Don't forget the backend:

• Delete unused Silverlight XAP files, related scripts, and styles from your server
• Ensure your server's HTTP response headers don't include any Silverlight-related identifiers (like custom X-Powered-By tags tied to Silverlight)

Pro tip: Before going live, test thoroughly across all Edge channels (Stable, Beta, Dev) to confirm the vintage warning is gone, and double-check that your HTML5 player streams smoothly on both IE11 and Edge.
