Deploy CDN URL rewriter mu-plugin and defer/print optimizer mu-plugin on the sandbox server (test.thelinguagroup.com) via SSH. Both files go inside the test-wp-wordpress-1 Docker container at /var/www/html/wp-content/mu-plugins/. Verify CDN rewriting, defer, and print/onload are all working.
Donna2026-06-01 19:33 UTC
I'll create both mu-plugin files, SSH them into the Docker container, and verify everything works. Let's start.

Both files created. Now let me SSH to the server, ensure the mu-plugins directory exists, and copy the files in.

Let me check the login page form action specifically, and also examine whether assets on the login page are the issue.

Donna2026-06-01 19:33 UTC
The form action correctly points to the origin (not CDN) ✅ — but assets on the login page are being served from CDN (16 references). The form POST is safe. However, to strictly match the verification criteria (0 CDN references on wp-login.php), I should add a login page check to skip all rewriting when on wp-login.php. Let me update the plugin.

## Summary
### What I did
Deployed two mu-plugins to the `test-wp-wordpress-1` Docker container on `212.132.99.138`:
1. **`profe-cdn.php`** — CDN URL rewriter that rewrites asset URLs to `test-thelinguagroup.b-cdn.net`
2. **`profe-perf-optimize.php`** — Defer/print optimizer that defers non-critical JS and applies print/onload pattern to non-critical CSS
### Files created/modified
- **`/root/profe-cdn.php`** (local) → **`/var/www/html/wp-content/mu-plugins/profe-cdn.php`** (in container)
- **`/root/profe-perf-optimize.php`** (local) → **`/var/www/html/wp-content/mu-plugins/profe-perf-optimize.php`** (in container)
### Verification results — ALL PASS ✅
| Check | Result | Status |
|-------|--------|--------|
| **PHP syntax** — both files | No errors | ✅ |
| **CDN URLs on homepage** | 44 references to `test-thelinguagroup.b-cdn.net` | ✅ |
| **Defer on homepage** | 22 occurrences of `defer` | ✅ |
| **Print/onload on homepage** | 8 occurrences of `media='print'`/`media=.print` | ✅ |
| **Login page CDN references** | 0 — no CDN URLs at all on `wp-login.php` | ✅ |
| **Login form action** | `https://test.thelinguagroup.com/wp-login.php` — origin, not CDN | ✅ |
| **HTTP status** | 200 — site loads fine | ✅ |
### Note
The CDN plugin includes a `$_SERVER['REQUEST_URI']` check to skip ALL rewriting when on `wp-login.php`, ensuring the login form's POST action and all page assets stay on origin. This was added to meet the strict verification criteria (0 CDN references on the login page).
