Fix provided in proxy server to clean multiple slashes and correctly redirect with HTTP 308
Description:
This PR updates the proxy server logic to:
• Detect multiple consecutive slashes (//, ///, etc.) in the incoming URL.
• Clean the URL by replacing extra slashes with a single slash.
• Redirect the browser using an HTTP 308 Permanent Redirect to the cleaned URL.
• Prevent forwarding malformed URLs to the Next.js application.
Previously, malformed URLs (with extra slashes) were either forwarded incorrectly or caused client-side router crashes with error message “Error: invariant: invalid relative URL, router received...”.
Tested:
• Manually tested with URLs like http://localhost:8000///about and http://localhost:8000///de/////about and confirmed redirection to http://localhost:8000/about and http://localhost:8000/de/about respectively.
• Confirmed correct behavior in incognito mode and after clearing browser cache.
• Tested proxy with HTTPS using sample PEM keys.
