Juliet Just Masks

Juliet Just Masks is a high-performance URL masking and reverse proxy mask manager for WordPress. While Romeo Redirect Manager handles open redirects, Juliet provides seamless stealth routing and URL masking. As a lightweight, native URL masker, Juliet lets WordPress act as a stealth reverse proxy. It intercepts specific incoming paths, keeps the visitor's address bar unchanged, and fetches/renders dynamic HTML, React/Vue SPAs, or external landing pages behind the scenes. Why use Juliet Mask Manager?

• Native URL Masking — Serve remote applications, microservices, and landing pages on your own custom domain without iframes or server configuration.
• Smart Mask Manager — Visual dashboard to create, manage, sort, search, and toggle active/inactive URL masks in real time.
• Fast Path Reverse Proxy — Zero-latency early route matching hooks before WP Query to proxy requests at top speed.
• SPA & <base> Tag Injector — Keeps relative script chunks, assets, and API requests properly routed through the proxy.
• Asset & Link Patcher — Rewrites root-relative URLs, internal CSS url() assets, and external navigation links into your local mask namespace.
• SSRF Protection & Security — Enterprise-grade IP and protocol validation protects your server from unsafe outbound requests.
• Companion to Romeo Redirect Manager — The complete routing suite: Romeo for redirection, Juliet for masking.

Features

• Stealth Routing Engine — Bypasses WP_Query to serve remote HTML without triggering a 404, supporting unlimited sub-paths.
• Mask Manager Dashboard — Intuitive card and list views with live search, custom dropdown filtering, and instant AJAX toggles.
• URL Masker & Link Masking — Automatically rewrites remote URLs and same-origin links into your local slug namespace.
• Asset Dependency Patcher — Rewrites root-relative asset paths (/css/style.css, srcset, inline url(), data-src) on the fly.
• Proxy Header Passthrough — Forwards visitor IP (X-Forwarded-For), User-Agent, language, and protocol for accurate analytics.
• SSRF Protection — Validates protocols, credentials, and DNS against private IP ranges.
• DOM <base> Injector — Smart <base href> injection tailored for complex JavaScript/AJAX-heavy SPAs.
• Asset Caching & MIME Typing — Built-in static asset caching headers and strict MIME type detection for scripts and styles.
• Graceful Failsafe — Theme-native 404 fallback if a remote server is unreachable.
• Method Pass-Through — Supports GET, POST, PUT, PATCH, DELETE, and CORS OPTIONS preflight requests.

Example

1. Go to Juliet Just Masks in wp-admin.
2. Click Create New Mask.
3. Enter the Local Path: marketing-hub.
4. Enter the Remote Target URL: https://external-landing-page.com/promo-1.
5. Save.

Visiting yoursite.com/marketing-hub now renders the remote landing page while the address bar still shows yoursite.com/marketing-hub. Deeper paths work too: yoursite.com/marketing-hub/pricing proxies the remote app's /pricing route. Known limitations

• CORS — if the remote server sends strict CORS headers for its assets, browsers may block cross-origin subresources. The remote must allow your domain (or serve assets with permissive CORS).
• Remote sessions — Set-Cookie responses are not forwarded (cookies would be scoped incorrectly). Authenticated remote applications need additional cookie handling; forwarding the visitor's cookies upstream is available via the juliet_forward_cookies filter but leaks this site's auth cookies, so only enable it for trusted targets.
• DNS rebinding — SSRF validation resolves DNS separately from the fetch. A hostile target could rotate DNS between check and fetch. Only mask targets you control or trust.
• Lazy-loaded assets — attributes such as data-src set by JavaScript after load cannot be patched server-side; enable <base> injection for those apps.

1. Upload the juliet-just-masks folder to /wp-content/plugins/, or install via the Plugins screen.
2. Activate Juliet Just Masks through the Plugins menu (the registry table is created automatically).
3. Navigate to Juliet Just Masks in the admin menu and create your first mask.

If routes return 404s after manual database edits, visit Settings → Permalinks once to flush rewrite rules.
