OVH环境下bubbleio.fr响应式正常但bubbleio.net跳转后异常排查

Hey there, let's dig into why your bubbleio.net redirected page isn't behaving responsively, even though bubbleio.fr works perfectly and the underlying code/server are identical. Here are actionable troubleshooting leads to check:

1. Verify OVH Redirect Type & Configuration #

• OVH offers different redirect modes, and masked redirects (also called "cloaked" redirects) are a common culprit here. This mode wraps your target page in an iframe, which can break viewport settings and responsive behavior since the iframe's own viewport might not inherit the parent page's responsive rules.
• Check your OVH control panel: Ensure you're using a standard 301 (permanent) or 302 (temporary) redirect instead of a masked one. Masked redirects are often labeled as "Redirect with masking" or similar—switch to a direct redirect if that's the case.

2. Compare Viewport Meta Tag Across Both Domains #

Even if your code is identical, server-side logic might alter the <meta name="viewport"> tag based on the incoming request's Host header.

• On both domains, use your browser's developer tools (right-click → "View Page Source" or inspect element) to check the viewport tag. It should look something like this for proper responsive behavior:

  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  

• If the .net version lacks this tag or has a different value, your server might be serving modified content based on the Host header—check your OVH site configuration or any server-side scripts that could be doing this.

3. Clear Browser & CDN Caches #

Cached content can cause old, non-responsive versions of your .net page to load even after you've set up the redirect:

• Test the .net page in a private/incognito browser window to bypass local browser cache.
• Force a hard refresh (Ctrl+Shift+R on Windows/Linux, Cmd+Shift+R on Mac) to clear cached assets for the .net domain.
• If you're using OVH's CDN service, log into your OVH dashboard and manually purge the CDN cache for both domains to ensure fresh content is served.

4. Check HTTP Request Headers & Server Responses #

The Host header sent when accessing .net might trigger different server behavior:

• Open your browser's Network tab in developer tools, load both .fr and .net pages, and compare the request headers (specifically the Host field).
• Verify that the server returns identical HTML, CSS, and JavaScript files for both domains. If certain responsive CSS files are missing or modified for .net, this would break the layout.

5. Test Across Multiple Mobile Browsers #

Some mobile browsers handle redirects or viewport settings differently:

• Test the .net page on popular mobile browsers (Chrome, Safari, Firefox for Android/iOS) to see if the issue is browser-specific. If it only happens in one browser, it might be a browser-specific quirk with how it handles the redirect and viewport.
