URL Rewriting Test Page

+ +
+

Current URL

+ + {currentUrl || 'Loading...'} + +
+ +
+

Test Subdomain Links

+

These links should render with subdomain URLs when rewrites are configured:

+
    +
  • + + App1 Subdomain → /subdomain/app1 + + {linkHrefs.app1 && ( + + (renders as: {linkHrefs.app1}) + + )} +
    • +
  • + + App2 Dashboard → /subdomain/app2/dashboard + + {linkHrefs['app2-dashboard'] && ( + + (renders as: {linkHrefs['app2-dashboard']}) + + )} +
    • +
  • + + Test About → /subdomain/test/about + + {linkHrefs['test-about'] && ( + + (renders as: {linkHrefs['test-about']}) + + )} +
    • +
+
+ +
+

Test Path Rewrites

+

These demonstrate path-based rewrites:

+
    +
  • + + Regular docs link → /docs/intro (no rewrite) + +
    • +
  • + + Old docs link → /old-docs/intro (should rewrite to /docs/intro) + +
    • +
+
+ +
+

Test Middleware Response

+

Test that middleware can return responses directly:

+ + + {middlewareResponse && ( + 
+            {JSON.stringify(middlewareResponse, null, 2)}
+
+ )} +
+ +
+

Testing Instructions

+
    +
  1. + Test subdomain routing locally: +
      +
    • Visit http://app1.localhost:6173
      • +
    • Should show the subdomain page with "app1" as the subdomain
      • +
    +
    2. +
  2. + Test Link rendering: +
      +
    • Check the "renders as:" text next to each link above
      • +
    • Subdomain links should show as *.localhost URLs if rewrites are working
      • +
    +
    3. +
  3. + Test navigation: +
      +
    • Click on subdomain links
      • +
    • Should navigate correctly with proper URL in address bar
      • +
    +
    4. +
  4. + Test middleware response: +
      +
    • Click the button above
      • +
    • Should receive JSON response directly from middleware
      • +
    +
    5. +
+
+ +
+

Direct Subdomain Test URLs

+

The .localhost domain automatically resolves to 127.0.0.1 on modern systems.

+

Try these URLs directly in your browser:

+ +
+ +
+
